CY54FCT163TLMB

Counter Dividers Overview

The CY54FCT163TLMB is a high-speed synchronous modulo-16 binary counter manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55°C to 125°C. The device features a 20-pin LCCC package with a propagation delay maximum of 11.5 ns. It provides 32-mA output sink current and 12-mA output source current, ensuring compatibility with FCT and F logic standards.

Counter Dividers Feature Summary

• Synchronous presettable design for programmable divider applications
• Ioff circuitry enables partial-power-down mode operation
• Edge-rate control circuitry improves noise characteristics
• Fully compatible with TTL input and output logic levels

Counter Dividers Applications

• Programmable frequency dividers
• Synchronous multistaged counters
• High-speed digital timing circuits

Counter Dividers Procurement Notes

Verify the specific ordering suffix TLMB confirms the ceramic LCCC package variant. Confirm the MIL-PRF-38535 compliance status if required for your application, as testing protocols may differ for production versus military-grade parts. Ensure all unused inputs are tied to VCC or GND to maintain proper device operation.

Counter Dividers Selection Notes

Select this component when a robust, high-speed synchronous counter is needed for wide temperature environments. The CY54FCT163T variant offers lower drive currents compared to the CY74FCT163T series. Consider the LCCC package constraints regarding PCB layout and thermal management during the design phase.

Counter Dividers Part Context

This part belongs to the ’FCT163T family of 4-bit binary counters. It shares functional pinouts with other devices in the series but differs in drive strength and package options. The CY54FCT163TLMB specifically denotes the military-grade ceramic version designed for harsh environmental conditions.

Counter Dividers FAQ

How does the Ioff feature benefit the device?

The Ioff circuitry disables outputs to prevent damaging current backflow through the device when it is powered down, supporting partial-power-down applications.

What is the function of the CEP and CET inputs?

CEP (Count-enable parallel) and CET (Count-enable trickle) are count-enable inputs that allow versatile formation of synchronous multistaged counters.
