SY100E154JC

Signal Switches, Multiplexers, Decoders Overview

The SY100E154JC is a high-performance ECL component featuring five 2:1 multiplexers followed by latches with differential outputs. It operates within an extended VEE range of –4.2V to –5.5V and utilizes a 28-pin PLCC package. The device supports asynchronous master reset and dual latch-enable signals. Propagation delays are specified at 700ps maximum for data inputs and 750ps for latch enable, ensuring compatibility with industry-standard 100K ECL levels.

Signal Switches, Multiplexers, Decoders Feature Summary

• Features five 2:1 multiplexers integrated with latches providing differential true and inverted outputs
• Supports asynchronous master reset to force all Q outputs to logic LOW
• Utilizes dual latch-enable signals (LEN1, LEN2) that are logically OR-gated for control
• Includes internal 75KΩ input pulldown resistors for signal stability
