SY10E016JC

Overview

The SY10E016JC is an 8-bit synchronous binary up counter from the 10E series, manufactured by Microchip Technology. It operates within a VEE range of –4.2V to –5.5V and supports a minimum count frequency of 700MHz. The device features a maximum propagation delay of 1000ps from CLK to Q/TC outputs. It includes internal gated TC feedback for programmable counting, asynchronous master reset, and parallel load capabilities. The component is housed in a 28-pin PLCC package.

Feature Summary

• Supports high-speed synchronous counting with internal terminal count feedback for programmable division
• Provides asynchronous master reset and parallel preset data loading functions
• Features fully compatible I/O levels with industry standard 10KH and 100K ECL families

Applications

• High-performance ECL system counters
• Cascaded multi-bit counter implementations
• Programmable frequency dividers

Procurement Notes

Verify the specific commercial temperature grade associated with the JC suffix against current manufacturer specifications. Confirm that the 28-pin PLCC package aligns with target PCB footprint requirements. Ensure power supply rails match the specified negative voltage range for proper operation.

Selection Notes

Select this component when designing systems requiring precise 8-bit binary counting at frequencies exceeding 700MHz. Consider its compatibility with existing MECL 10KH logic families if upgrading legacy designs. Evaluate the need for external gating only if cascading beyond 16 bits or implementing complex divider ratios.

Part Context

This part belongs to the Micrel 10E series of ECLinPS logic devices, now under Microchip Technology. It serves as a direct functional equivalent to the Motorola MC10E/100E016, maintaining architectural consistency with the MECL 10KH family while offering extended voltage ranges and enhanced speed characteristics for modern high-frequency applications.

FAQ

How does the TCLD pin function affect the counting behavior?

When TCLD is HIGH, internal feedback causes the counter to automatically reload parallel data upon reaching terminal count (all HIGH state), enabling programmable division.

What is the method for cascading multiple E016 devices?

Multiple devices can be cascaded by connecting the active low Terminal Count (TC) output to the Count Enable (CE) input of the subsequent stage, potentially using external OR gates for widths greater than 16 bits.
