DESCRIPTION

The 74F657 is an octal transceiver featuring non–inverting buffers with 3–state outputs and an 8–bit parity generator/checker, and is intended for bus–oriented applications.

FEATURES

• Combines 74F245 and 74F280A functions in one package

• High impedance base input for reduced loading (70µA in

high and low states)

• Ideal in applications where high output drive and light bus

loading are required (IIL is 70µA vs FAST std of 600µA)

• 3–state buffer outputs sink 64mA and source 15mA

• Input diodes for termination effects

• 24–pin plastic slim DIP (300mil) package

• Industrial temperature range available (–40°C to +85°C)
