100344
Low Power 8-Bit Latch with Cut-Off Drivers
General Description
The 100344 contains eight D-type latches, individual inputs
(D
), outputs (Q
), a common enable pin (E), latch enable
(LE), and output enable pin (OEN). 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.
A HIGH on OEN holds the outputs in a cut-off state. The
cut-off state is designed to be more negative than a normal
ECL LOW level. This allows the output emitter-followers to
turn off when the termination supply is 2.0V, presenting a
high impedance to the data bus. This high impedance re-
duces termination power and prevents loss of low state
noise margin when several loads share the bus.
The 100344 outputs are designed to drive a doubly termi-
nated 50
transmission line (25
load impedance). All in-
puts have 50 k
pull-down resistors.
