Overview
The SY100E141JC is an 8-bit full-function shift register designed for high-performance ECL systems. It supports serial/parallel in and serial/parallel out shifting in either direction. The device features four selectable modes: Load, Hold, Shift Left, and Shift Right. It operates with an extended VEE range of –4.2V to –5.5V and includes an asynchronous Master Reset. The component is available in a 28-pin PLCC package.
Feature Summary
- Supports bi-directional shifting with parallel data inputs D0-D7 and serial inputs DL/DR
- Provides four operational modes controlled by SEL0 and SEL1 pins
- Includes an asynchronous Master Reset pin to clear all registers
- Features internal 75KΩ input pulldown resistors
Applications
- High-performance ECL system designs
- Serial-to-parallel data conversion circuits
- Parallel-to-serial data conversion circuits
- Bi-directional data buffering applications
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and lead finish. Confirm that the commercial temperature range meets the environmental requirements of the target application. Ensure compatibility with existing board layouts due to the 28-pin PLCC form factor.
Selection Notes
Select this component when designing synchronous logic requiring 8-bit storage with flexible data loading options. The dual serial inputs allow for left or right shifting based on control signals. Verify that the power supply voltage aligns with the specified –4.2V to –5.5V range for proper operation.
Part Context
This part belongs to the SY10/100E141 family of 8-bit shift registers manufactured by Micrel (now Microchip Technology). It is fully compatible with industry standard 10KH and 100K ECL levels. The device is also pin-compatible with the E241 variant.
Replacement Considerations
The SY10E141JC is a direct replacement for the SY100E141JC within the same package and electrical specifications. Both variants share identical functionality and pinouts.
