SN74ABT657ADWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT657ADWR is an octal transceiver with parity generators/checkers and 3-state outputs. It operates on a 4.5 V to 5.5 V supply voltage within a -40°C to +85°C temperature range. The device features high-drive outputs capable of -32 mA IOH and 64 mA IOL. Propagation delays from A or B ports are typically 1 ns to 4.6 ns, while parity generation delays reach up to 8.1 ns. It utilizes a flow-through architecture in a 24-pin SOIC (DW) package.
