100344  
Low Power 8-Bit Latch with Cut-Off Drivers  
The 100344 outputs are designed to drive a doubly termi-  
nated 50transmission line (25load impedance). All in-  
puts have 50 kpull-down resistors.  
General Description  
The 100344 contains eight D-type latches, individual inputs  
(Dn), outputs (Qn), 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.

n Drives 25load  
n Low power operation  
n 2000V ESD protection  
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.
