| Micrel, Inc. 3-BIT 4:1 MUX-LATCH SY10E256 SY100E256 SY10E256 SY100E256 FEATURES s 950ps max. data to output s Extended 100E VEE range of -4.2V to -5.5V s s s s 850ps max. latch enable to output Separate select controls Differential outputs Fully compatible with industry standard 10KH, 100K ECL levels s Internal 75K input pulldown resistors s Fully compatible with Motorola MC10E/100E256 s Available in 28-pin PLCC package DESCRIPTION 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). When the Latch Enable (LEN) is at a logic LOW, the latch is transparent and output data is controlled by the multiplexer select controls. A logic HIGH on LEN latches the outputs. The Master Reset (MR) overrides all other controls to set the Q outputs LOW.
