SN74HCT245ANS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT245ANS is an octal bus transceiver manufactured by Texas Instruments, belonging to the HCT logic series. It features eight bidirectional data channels with three-state outputs, designed for asynchronous communication between data buses. The device operates within a supply voltage range of 4.5V to 5.5V and supports TTL-compatible input levels with CMOS output characteristics. Direction control determines data flow between A and B buses, while the output enable input isolates the device when disabled.
