DESCRIPTION
The 74LAS651 and 74ALS652 transceivers/registers consist of bus
transceiver circuits with 3-State outputs, D-type flip-flops, and
control circuitry arranged for multiplexed transmission of data
directly from the input bus or the internal registers. Data on the A or
B bus will be clocked into the registers as the appropriate clock pin
goes High. Output enable (OEAB, OEBA) and select (SAB, SBA)
pins are provided for bus management. The 74LAS651-1 and
74ALS652-1 will sink 48mA if the V
CC
is limited to 5.0V
±
0.25V.
