Bus Hold on Data Inputs Eliminates the Need
for External Pullup/Pulldown Resistors
This 32-bit edge-triggered D-type flip-flop is designed for 1.65-V to 3.6-V VCC operation.
The SN74ALVCH32374 is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus
drivers, and working registers. It can be used as four 8-bit flip-flops, two 16-bit flip-flops, or one 32-bit flip-flop. On
the positive transition of the clock (CLK) input, the Q outputs of the flip-flop take on the logic levels at the data
(D) inputs. The output-enable (OE) input can be used to place the eight outputs in either a normal logic state
(high or low logic levels) or the high-impedance state. In the high-impedance state, the outputs neither load nor
drive the bus lines significantly. The high-impedance state and the increased drive provide the capability to drive
bus lines without need for interface or pullup components.
OE does not affect internal operations of the flip-flop. 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 VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors
with the bus-hold circuitry is not recommended.
