SN74LV245ATPWR | Octal Bus Transceiver | 3-State Bidirectional Logic IC | Texas Instruments (TI)

Product Overview

     The SN74LV245ATPWR from Texas Instruments is a low-voltage octal bus transceiver featuring 3-state outputs and direction control.
     It is built using advanced 3.3V CMOS technology and supports TTL-compatible inputs.
     With the DIR pin controlling data direction between the A and B buses, and the OE pin enabling high-impedance outputs, it provides flexible data routing and bus isolation.
     Operating from 2.0V to 5.5V, the SN74LV245A delivers a typical propagation delay of 6 ns at 3.3V, making it ideal for industrial control, MCU/FPGA interfaces, logic level translation, and bidirectional communication buses.
     It is packaged in a TSSOP-20 (PW) for compact PCB designs.
