description/ordering information
This octal transparent D-type latch is designed for 1.65-V to 3.6-V V
CC
operation.
The SN74ALVCH373 is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus
drivers, and working registers. While the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs.
When LE is taken low, the Q outputs are latched at the logic levels set up at the D inputs.
A buffered 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 increased drive provide the capability to drive bus
lines without interface or pullup components.
OE does not affect the internal operations of the latches. 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.
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.
