Quadruple Bus Transceivers with 3-State Outputs

These quadruple bus transceivers are designed for asynchronous two-way communications between

data buses. The control function implementation allows for maximum ﬂexibility in timing. These

devices allow data transmission from the A bus to the B bus or from the B bus to the A bus depending

upon the logic levels at the enable inputs (GBA and GAB). The enable inputs can be used to disable

the device so that the buses are effectively isolated.

The dual-enable conﬁguration gives the quadruple bus transceivers the capability to store data

by simultaneous enabling of GBA and GAB. Each output reinforces its input in this transceiver

conﬁguration. Thus, when both control inputs are enabled and all other data sources to the two sets

of bus lines are at high impedance, both sets of bus lines (8 in all) will retain their states. The 4-bit

codes appearing on the two sets of buses will be complimentary for the ‘ALS242 and ‘AS242 or

identical for the ‘ALS243 and ‘AS243.
