100343
Low Power 8-Bit Latch
General Description
The 100343 contains eight D-type latches, individual
inputs, (Dn), outputs (Qn), a common enable pin (E), and a
latch enable 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 50termina-
tion resistor to 2.0V. All inputs have 50 kpull-down
resistors.
