description
The ’ABT32373 is a 32-bit (quad 8-bit) transceiver with D-type latches and 3-state outputs designed specifically
for driving highly capacitive or relatively low-impedance loads. It is particularly suitable for implementing buffer
registers, I/O ports, bidirectional bus drivers, and working registers. The device can be used as four 8-bit
transceivers, two 16-bit transceivers, or one 32-bit transceiver. It allows data transmission from the A bus to the
B bus or from the B bus to the A bus depending upon the logic level at the output-enable inputs.
The output-enable (OEAB or OEBA) inputs do not affect internal operations of the latch. Old data can be retained
or new data can be entered while the outputs are in the high-impedance state.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver (A to B).
OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the
current-sourcing capability of the driver (B to A).
Active bus-hold circuitry is provided to hold unused or floating inputs at a valid logic level.
The SN54ABT32373 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74ABT32373 is characterized for operation from –40
°
C to 85
°
C.
