74F657
Octal Bidirectional Transceiver with
8-Bit Parity Generator/Checker and 3-STATE Outputs
General Description
The 74F657 contains eight non-inverting buffers with 3-
STATE outputs and an 8-bit parity generator/checker. It is
intended for bus-oriented applications. The buffers have a
guaranteed current sinking capability of 24 mA at the A
Port and 64 mA at the B Port.
