MC10H141L

Shift Registers Overview

The MC10H141 is a four-bit universal shift register from the MECL 10H series, offering functional and pinout compatibility with standard MECL 10K parts. It delivers a minimum shift frequency of 250 MHz with typical power dissipation of 425 mW. The device features improved noise margins of 150 mV over the operating voltage and temperature range. Electrical characteristics are defined at VEE = -5.2 V ±5%, with propagation delays ranging from 1.0 to 2.1 ns depending on temperature. It supports parallel entry, shift left, shift right, and stop shift operations controlled by S1 and S2 select inputs.

Shift Registers Feature Summary

• Supports shift left, shift right, parallel entry, and hold modes via S1/S2 control inputs without external gating
• Provides 150 mV improved noise margin across operating voltage and temperature ranges
• Voltage compensated design compatible with MECL 10K logic families
• Shifts data on the positive edge of the clock input

Shift Registers Applications

• High-speed serial-to-parallel conversion in communication systems
• Parallel-to-serial data transmission interfaces
• Digital signal processing delay lines
• Data buffering in high-frequency logic circuits

Shift Registers Procurement Notes

Verify the specific package suffix (P for PDIP-16 or FN for PLLC-20) matches your board layout requirements. Confirm RoHS compliance status if environmental regulations apply. Ensure supply voltage is strictly maintained at -5.2 V ±5% for specified electrical performance. Check thermal management needs as power dissipation is approximately 425 mW. Validate that input/output levels align with existing MECL 10K system constraints.

Shift Registers Selection Notes

Select this component when MECL 10K pinout compatibility is required alongside higher speed performance. The MC10H141 offers improved propagation delay compared to legacy 10K parts without increasing power consumption. Consider the available packages: PDIP-16 for through-hole applications or PLLC-20 for surface mount. Ensure the design can accommodate the negative supply voltage requirement typical of MECL logic families.

Shift Registers Part Context
