(DB), Thin Shrink Small-Outline (PW), and
Ceramic Flat (W) Packages, Ceramic Chip
Carriers (FK), and Standard Plastic (N) and
Ceramic (J) 300-mil DIPs
description
These 8-bit latches feature 3-state outputs
designed specifically for driving highly capacitive
or relatively low-impedance loads. They are
particularly suitable for implementing buffer
registers, I/O ports, bidirectional bus drivers, and
working registers.
The eight latches of the ’HC373 are transparent
D-type latches. 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 levels that were set up at the D inputs.
An output-enable (OE) input places 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 off.
The SN54HC373 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C. The
SN74HC373 is characterized for operation from –40
°
C to 85
°
C.
