MUX-LATCH

DESCRIPTION

FEATURES

■ 950ps max. data to output

The SY10/100E256 offer three 4:1 multiplexers followed

by latches with differential outputs designed for use in new,

high-performance ECL systems. Separate Select controls

are provided for the leading 2:1 mux pairs (see block

diagram).

■ Extended 100E VEE range of –4.2V to –5.5V

■ 850ps max. latch enable to output

■ Separate select controls

■ Differential outputs

When the Latch Enable (LEN) is at a logic LOW, the latch

istransparentandoutputdataiscontrolledbythemultiplexer

select controls. A logic HIGH on LEN latches the outputs.

The Master Reset (MR) overrides all other controls to set

the Q outputs LOW.

■ Fully compatible with industry standard 10KH,

100K ECL levels

■ Internal 75KΩ input pulldown resistors

■ Fully compatible with Motorola MC10E/100E256

■ Available in 28-pin PLCC package
