74HC193N,652

Counter Dividers Overview

The NXP USA Inc. 74HC193N,652 is a 4-bit synchronous binary up/down counter housed in a 16-pin DIP package (SOT38-4). It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features separate count-up (CPU) and count-down (CPD) clock inputs that trigger state changes on the LOW-to-HIGH transition. It includes asynchronous parallel load (PL) and master reset (MR) capabilities, along with terminal count outputs (TCU and TCD) for cascading.

Counter Dividers Feature Summary

• Supports synchronous reversible 4-bit binary counting using separate CPU and CPD clock inputs.
• Features asynchronous parallel loading and asynchronous master reset functions.
• Includes expandable terminal count outputs (TCU and TCD) for multistage counter applications without external logic.

Counter Dividers Applications

• Multistage counter systems utilizing cascaded terminal count outputs
• Digital timing circuits requiring presettable synchronous counting
• Frequency division and waveform generation applications

Counter Dividers Procurement Notes

Verify the specific suffix '652' against the manufacturer's current ordering information to confirm the exact packaging variant and compliance status. Ensure the procurement documentation matches the DIP16 package designation (SOT38-4) required for the design. Confirm RoHS compliance details as specified in the latest product data sheet revision.

Counter Dividers Selection Notes

Select this component when a CMOS-level input compatible 4-bit bidirectional counter is required. The 74HC193N,652 is suitable for designs needing independent up and down clock control rather than a single direction pin. Consider the operating voltage range of 2.0 V to 6.0 V for compatibility with the system power rails and the wide industrial temperature range if applicable.

Counter Dividers Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices produced by NXP Semiconductors. The 74HC193 specifically provides synchronous 4-bit up/down counting functionality. The 'N' suffix indicates the Dual In-line Package (DIP), while '652' denotes the specific tape-and-reel or standard packaging configuration defined by the manufacturer.

Counter Dividers Replacement Considerations

The 74HCT193N,652 is a functional substitute within the same family, differing primarily in input level requirements (TTL vs. CMOS). Other package variants such as 74HC193D (SO16) or 74HC193PW (TSSOP16) offer the same logical function but require footprint adaptation.
