74ACT652
Transceiver/Register
General Description
The ACT652 consists of bus transceiver circuits with D-
type flip-flops, and control circuitry arranged for multiplexed
transmission of data directly from the input bus or from
internal registers. Data on the A or B bus will be clocked
into the registers as the appropriate clock pin goes to the
HIGH logic level. Output Enable pins (OEAB, OEBA) are
provided to control the transceiver function.
Features
s Independent registers for A and B buses
s Multiplexed real-time and stored data
s Outputs source/sink 24 mA
s TTL-compatible inputs
