Overview
The SY100E150JC is a 6-bit D latch manufactured by Micrel, Inc., designed for high-performance ECL systems. It features differential outputs and operates within an extended VEE range of –4.2V to –5.5V. The device includes internal 75KΩ input pulldown resistors and is fully compatible with industry standard 10KH and 100K ECL levels. It is available in a 28-pin PLCC package.
Feature Summary
- Features two independent latch enable inputs (LEN1, LEN2) that control the transparent mode or data latching state.
- Includes a Master Reset (MR) function that overrides other signals to set Q outputs to a logic LOW.
- Provides differential true and inverting outputs for use in new, high-performance ECL systems.
Applications
- High-performance ECL system designs
- Data storage applications requiring differential outputs
- Systems utilizing industry standard 10KH or 100K ECL levels
Procurement Notes
Verify component authenticity as the datasheet originates from Micrel, Inc. Confirm the specific ordering suffix matches the required lead finish, such as Sn-Pb or Matte-Sn Pb-Free variants. Ensure the package type corresponds to the 28-pin PLCC (J28-1) specification before procurement.
Selection Notes
Select this component for applications requiring 6-bit D latches with differential outputs. Consider the extended VEE operating range and compatibility with standard ECL levels. Verify temperature range requirements against the commercial specifications provided in the datasheet.
Part Context
The SY100E150JC belongs to the SY10/100E series of logic devices. It is functionally equivalent to the Motorola MC10E/100E150. The device is part of a family designed for high-speed digital applications using ECL technology.
Replacement Considerations
The Motorola MC10E/100E150 is a confirmed functional equivalent. Verify pinout and electrical characteristics match before substitution.
FAQ
How does the Master Reset function operate?
The Master Reset (MR) overrides all other signals to set the Q outputs to a logic LOW.
What is the purpose of the internal pulldown resistors?
The device includes internal 75KΩ input pulldown resistors to ensure stable input states.
