Texas Instruments Buffers, Drivers, Receivers, Transceivers 74ACT11543DWR

The 74ACT11543DWR is an 8-bit registered transceiver featuring two sets of D-type latches for bidirectional data flow. It supports TTL-voltage compatible inputs and has 3-state true outputs, allowing for flexible data management. The device includes separate latch enable and output enable inputs for independent control of data flow in both directions. It operates within a supply voltage range of 4.5V to 5.5V and is characterized for a temperature range of -40°C to 85°C. The transceiver is designed with a flow-through architecture that optimizes PCB layout and minimizes high-speed switching noise through center-pin VCC and GND configurations. It is built using an EPIC (Enhanced-Performance Implanted CMOS) 1-µm process, providing a typical latch-up immunity of 500 mA at 125°C. The product is available in a 28-pin SOIC package and is compliant with RoHS standards.
