Description
This octal bus transceiver is designed for asynchronous two-way communication between data buses. The control
function implementation allows for maximum flexibility in timing.
This device allows 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 these devices 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 (16 in all) will remain at
their last states. The 8-bit codes appearing on the two sets of buses will be identical for the HD74HC623 or
complementary for the HD74HC620.
Features
• High Speed Operation: tpd (Bus to Bus) = 12 ns typ (CL = 50 pF)
• High Output Current: Fanout of 15 LSTTL Loads (QA to QH outputs)
• Wide Operating Voltage: VCC = 2 to 6 V
• Low Input Current: 1 µA max
• Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
• Ordering Information
