HD74AC298/HD74ACT298

Quad 2-Input Multiplexer with Storage

ADE-205-389 (Z)

1st. Edition

Sep. 2000

Description

This device is a high-speed multiplexer with storage. It selects four bits of data from two sources (Ports)

under the control of a common Select input (S). The selected data is transferred to the 4-bit output register

synchronous with the HIGH-to-LOW transition of the Clock input (CP). The 4-bit register is fully edge

triggered. The Data inputs (I₀and I₁) and Select input (S) must be stable only one setup time prior to the

HIGH-to-LOW transition of the clock for predictable operation.
