SY100E156JC

Signal Switches, Multiplexers, Decoders Overview

The SY100E156JC is a 3-bit 4:1 multiplexer-latch integrated circuit manufactured by Microchip Technology, housed in a 28-lead PLCC package. It operates within an extended VEE range of –4.2V to –5.5V and features differential outputs. The device includes three independent 4:1 muxes with dual latch enables (LEN1, LEN2) and an asynchronous Master Reset (MR). Propagation delays from data inputs reach a maximum of 900ps, while select and latch enable signals exhibit delays up to 1050ps and 800ps respectively.

Signal Switches, Multiplexers, Decoders Feature Summary

• Integrates three 4:1 multiplexers followed by latches with differential outputs for high-performance ECL systems
• Features dual latch enable signals gated through a logical OR operation to control transparency or latching states
• Includes an asynchronous Master Reset signal that forces all outputs to a logic LOW state
• Contains internal 75KΩ input pulldown resistors and maintains full compatibility with industry standard 10KH and 100K ECL levels
