100343 Low Power 8-Bit Latch
August 1998
100343
Low Power 8-Bit Latch
General Description
The 100343 contains eight D-type latches, individual inputs,
(D
n
), outputs (Q
n
), a common enable pin (E), and a latch en-
able pin (LE). A Q output follows its D input when both E and
LE are LOW. When either E or LE (or both) are HIGH, a latch
stores the last valid data present on its D input prior to E or
LE going HIGH.
The 100343 outputs are designed to drive a 50Ω termination
resistor to −2.0V. All inputs have 50 kΩ pull-down resistors.
