Order Information ：
Part Number：LM293DR
Manufacturer：Texas Instruments
Category ：Integrated Circuits Linear - Comparators
Description ：IC COMPARATOR DIFF DUAL 8SOIC
Detailed Description：Comparator Differential CMOS, MOS, Open-Drain, TTL 8-SOIC
Applications：Vacuum robot / Single phase UPS / Server PSU / Cordless power tool / Wireless infrastructure / Applicances / Building automation / Factory automation & control / Motor drives / Infotainment & cluster.
The LM393B and LM2903B devices are the next generation versions of the industry-standard LM393 and LM2903 comparator family. These next generation B-version comparators feature lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2 kV ESD performance and input ruggedness through dedicated ESD clamps. The LM393B and LM2903B can drop-in replace the LM293, LM393 and LM2903, for both "A" and "V" grades.
All devices consist of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages.
Quiescent current is independent of the supply voltage.
Part Number：74LVC1G125GW
Manufacturer：Nexperia USA Inc.
Category ：Integrated Circuits Logic - Buffers, Drivers, Receivers, Transceivers
Description ：IC BUF NON-INVERT 5.5V 5TSSOP
Detailed Description：Buffer, Non-Inverting 1 Element 1 Bit per Element 3-State Output 5-TSSOP
The 74LVC1G125 provides one non-inverting buffer/line driver with 3-state output.
The 3-state output is controlled by the output enable input (OE). A HIGH-level at pin OE causes the output to assume a high-impedance OFF-state.
The input can be driven from either 3.3 V or 5 V devices. This feature allows the use of this device in a mixed 3.3 V and 5 V environment.
This device is fully specified for partial power-down applications using IOFF . The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
Part Number：TPS2041BDBVT
Manufacturer：Texas Instruments
Category ：Integrated Circuits PMIC - Power Distribution Switches, Load Drivers
Description ：IC PWR SWITCH N-CHAN 1:1 SOT23-5
Detailed Description：Power Switch/Driver 1:1 N-Channel 500mA SOT-23-5
Applications：Heavy Capacitive Loads / Short-Circuit Protections.
The TPS20xxB power-distribution switches are intended for applications where heavy capacitive loads and short circuits are likely to be encountered.
These devices incorporates 70-mΩ N-channel MOSFET power switches for power-distribution systems that require multiple power switches in a single package. Each switch is controlled by a logic enable input. Gate drive is provided by an internal charge pump designed to control the power-switch rise times and fall times to minimize current surges during switching. The charge pump requires no external components and allows operation from supplies as low as 2.7 V.
When the output load exceeds the current-limit threshold or a short is present, the device limits the output current to a safe level by switching into a constant-current mode, pulling the overcurrent (OCx) logic output low. When continuous heavy overloads and short circuits increase the power dissipation in the switch, causing the junction temperature to rise, a thermal protection circuit shuts off the switch to prevent damage. Recovery from a thermal shutdown is automatic once the device has cooled sufficiently.
Internal circuitry ensures that the switch remains off until valid input voltage is present. This powerdistribution switch is designed to set current limit at 1A (typical).
Part Number：SN74HC595N
Manufacturer：Texas Instruments
Category ：Integrated Circuits Logic - Shift Registers
Description ：IC 8-BIT SHIFT REGISTER 16-DIP
Detailed Description：Shift Shift Register 1 Element 8 Bit 16-PDIP
Function：Serial to Parallel, Serial
Applications：Network switches / Power infrastructure / LED displays / Servers.
The SNx4HC595 devices contain an 8-bit, serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has parallel 3- state outputs. Separate clocks are provided for both the shift and storage register. The shift register has a direct overriding clear (SRCLR) input, serial (SER) input, and serial outputs for cascading. When the output-enable (OE) input is high, the outputs are in the high-impedance state.
Part Number：BGA524N6
Manufacturer：Infineon Technologies
Category ：RF/IF and RFID RF Amplifiers
Description ：IC AMP GPS 1.55-1.615GHZ TSNP6-2
