74F160APC

Overview

The onsemi 74F160APC is a high-speed synchronous BCD decade counter operating in the 8421 sequence. It features a 16-pin Plastic Dual-In-Line Package (PDIP) and supports a supply voltage range of +4.5V to +5.5V. The device includes an asynchronous Master Reset input that forces outputs LOW, alongside Count Enable Parallel (CEP) and Trickle (CET) inputs for versatile multistage configurations. It operates within a temperature range of 0°C to +70°C.

Feature Summary

• Synchronous counting and loading capabilities with D-type edge-triggered flip-flops
• Asynchronous Master Reset input that overrides all other control signals
• High-speed synchronous expansion using Terminal Count output for multistage counters

Applications

• Programmable frequency dividers
• Synchronous multistage counter systems
• BCD sequence generation circuits

Procurement Notes

Verify the package type matches the required PCB footprint, as this component is available in multiple form factors including SOIC and SOP. Confirm the specific suffix indicates the PDIP variant. Ensure the design accounts for the asynchronous reset behavior distinct from the F162A model. Check for RoHS compliance status if environmental regulations apply to the target assembly process.

Selection Notes

Select this component when a synchronous BCD decade counter with asynchronous reset is required. It differs from the 74F162A by utilizing an asynchronous Master Reset rather than a synchronous one. Consider the 74F series speed characteristics and power consumption relative to system requirements. Verify compatibility with existing logic families regarding voltage levels and fan-out specifications.

Part Context

This part belongs to the 74F logic family, known for high-speed performance compared to standard TTL. It is functionally related to the 74F162A, which shares similar counting features but employs a synchronous reset mechanism. The device serves as a fundamental building block for digital timing and sequencing applications requiring precise modulo-10 counting operations.

Replacement Considerations

SN74F160AN from Texas Instruments is listed as a parameter equivalent substitute.
