SY10E150 SY100E150 SY10E150 6-BIT D LATCH Micrel, Inc. DESCRIPTION FEATURES ■ 700ps max. propagation delay ■ Extended 100E VEE range of –4.2V to –5.5V The SY10/100E150 are 6-bit D latches with differential outputs designed for use in new, high- performance ECL systems. When both Latch Enables (LEN1, LEN2) are at a logic LOW, the latch is in the transparent mode and input data propagates through to the output. A logic HIGH on either LEN1 or LEN2 (or both) latches the input data. The Master Reset (MR) overrides all other signals to set the Q outputs to a logic LOW. ■ Differential outputs ■ Fully compatible with industry standard 10KH, 100K ECL levels ■ Internal 75KΩ input pulldown resistors ■ Fully compatible with Motorola MC10E/100E150 ■ Available in 28-pin PLCC package BLOCK DIAGRAM D0 PIN NAMES D R D1 D R D2 D R D3 D R D5 Pin Q0 Q0 Q1 Q1 Q2 Function D0–D5 Data Inputs LEN1, LEN2 Latch Enables MR Master Reset Q0–Q5 True Outputs Q0–Q5 Inverting Outputs VCCO VCC to Output Q2 Q3 D R D4 SY100E150 D R Q3 Q4 Q4 Q5 Q5 LEN1 LEN2 MR M9999-032006 [email protected] or (408) 955-1690 Rev.: F 1 Amendment: /0 Issue Date: March 2006 SY10E150 SY100E150 Micrel, Inc.
