DESCRIPTION/ORDERING INFORMATIONThis 16-bit D-type latchis designed for
1.65-Vto 3.6-VVCC operation.
The SN74ALVCH16373is particularly suitable for
implementing buffer registers, I/O ports, bidirectional
bus drivers, working registers. This device can used as two 8-bit latches or one 16-bit latch.
When the (LE) inputis high, theQ
outputs follow the data (D) inputs. When LEis taken
low, theQ are latchedat the levels setupat
theD inputs. buffered (OE) input can be usedto
place the eight outputsin eithera normal logic state
(highor low levels)or the high-impedance state. the high-impedance state, the outputs neither
load nor the buslines significantly. The
high-impedance state and the increased drive provide
the capabilityto drive bus lines without need for
interfaceor components. OE does not affect
internal operations of the latch. Old data can be
retained or data can be entered while the
outputs are the high-impedance state.
resistor; the valueof the resistoris determined the current-sinking capabilityof the driver.
Active bus-hold circuitry holds unusedor undriven inputsata valid logic state. Useof pullupor pulldown resistors the bus-hold circuitryis not recommended.
