74HCT160N,652

Counter Dividers Overview

The NXP USA Inc. 74HCT160N,652 is a synchronous presettable BCD decade counter with an internal look-ahead carry and asynchronous reset. It operates on the positive-going edge of the clock (CP) to simultaneously clock all flip-flops. The outputs (Q0 to Q3) can be preset HIGH or LOW via data inputs (D0 to D3). A LOW at the parallel enable input (PE) disables counting and loads data on the clock edge. An asynchronous master reset (MR) sets all outputs LOW regardless of other inputs. Both count enable inputs (CEP and CET) must be HIGH for counting, and CET feeds forward to the terminal count output (TC) for cascading.

Counter Dividers Feature Summary

• Synchronous counting and loading mechanism
• Internal look-ahead carry simplifies serial cascading
• Asynchronous reset function independent of clock signals

Counter Dividers Applications

• BCD decade counting applications
• Digital frequency division circuits
• Time-base generation in digital clocks

Counter Dividers Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature range. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the component meets JEDEC standard no. 7A requirements for your design specifications before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a synchronous BCD decade counter with asynchronous clear is required. It is suitable for designs needing simple cascading capabilities via the terminal count output. Verify that the operating voltage and temperature ranges align with the system environment constraints.

Counter Dividers Part Context

This device belongs to the 74HC/HCT logic family, which provides high-speed Si-gate CMOS technology. It is pin-compatible with low power Schottky TTL (LSTTL) standards. The component is specified in compliance with JEDEC standard no. 7A, ensuring interoperability within standard digital logic systems.

Counter Dividers Replacement Considerations

Check for equivalent parts from other manufacturers that support the same HCT logic levels and DIP-16 packaging. Verify functional compatibility regarding the asynchronous reset and synchronous load operations.
