FEATURES
750ps max. LEN to output Extended 100E VEE range of –4.2V to –5.5V 700ps max. D to output Single-ended outputs Asynchronous Master Reset Dual latch-enables Fully compatible with industry standard 10KH, 100K ECL levels Internal 75KΩ input pulldown resistors Fully compatible with Motorola MC10E/100E155 Available in 28-pin PLCC package DESCRIPTION
If either LEN1 or LEN2 (or both) are at a logic HIGH, the outputs are latched. The multiplexer operation is controlled by the SEL (Select) signal which selects one of the two bits of input data at each mux to be passed through. The MR (Master Reset) signal operates asynchronously to take all outputs to a logic LOW.
