SN74LVC245APWR | TI Eight-Channel Bus Transceiver | 3-State | Low-Power High-Speed ​​Logic Chip

Product Overview

     The SN74LVC245APWR from Texas Instruments (TI) is an octal bidirectional bus transceiver with 3-state outputs and direction (DIR) control, designed for high-speed and low-power data bus interfacing. Operating from a 2.7 V to 3.6 V supply, it offers fast switching (typical 6 ns @ 3.3 V) and low quiescent current, providing robust logic isolation and efficient data buffering in multi-bus systems.

     Packaged in a TSSOP-20 (PW) form factor, it supports TTL input compatibility, high noise immunity, and full 3-state control via the OE pin. Ideal for use in communication systems, industrial control modules, and microcontroller bus extensions.
