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 VCC is limited to 5.0V ± 0.25V.

BUS MANAGEMENT FUNCTIONS
The following examples demonstrate the four fundamental
bus-management functions that can be performed with the
74ALS651/74ALS651-1 and 74ALS652/74ALS652-1. The select
pins determine whether data is stored or transferred through the
device in real time. The output enable pins determine the direction of
the data flow.

2. All typical values are at VCC = 5V, Tamb = 25°C.
3. For I/O ports, the parameter IIH and IIL include the off-state current.
4. The output conditions have been chosen to produce a current that closely approximates one half of the true short-circuit output current, IOS.
