The SN74LVC543ADW is an 8-bit non-inverting transceiver with latches from Texas Instruments, part of the 74LVC family. It operates from 1.65V to 3.6V, providing 24mA drive current. The integrated latches enable data storage, while 3-State outputs support bus sharing. Housed in a 24-SOIC package, it is perfect for industrial, telecom, and computing applications requiring reliable data buffering.
- Integrated Latches: Stores data temporarily, reducing external flip-flop requirements.
- Bidirectional Operation: Handles data flow in both directions, simplifying bus design.
- Low-Voltage Range (1.65V-3.6V): Compatible with multiple logic levels.
- 3-State Outputs: Prevents bus contention in multi-device systems.
Latch-Based Data Storage
Use the built-in latches to temporarily store data on a bus, ideal for interfacing slow peripherals with fast processors.
Bidirectional Bus Transceiver
In microcontroller systems, it connects two 3.3V buses, allowing data flow in both directions with 3-State control.
Level Shifting with Latching
It can shift between 1.8V and 3.3V domains while latching data, useful in multi-voltage sensor interfaces.
Industrial Control Register
In PLCs, it latches output control words from the CPU to drive actuators, ensuring stable signals during updates.
Memory Interface Buffering
For SRAM or EEPROM, it buffers address/data lines and latches them to meet setup/hold timing requirements.
Telecom Line Card Interface
In networking equipment, it buffers and latches control signals between line cards and the backplane, operating reliably at 3.3V.
