SN74HC193NE4

Counter Dividers Overview

The SN74HC193NE4 is a 4-bit synchronous reversible up/down binary counter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40°C to +85°C. The device features asynchronous clear, parallel asynchronous load for modulo-N counting, and look-ahead circuitry for cascading without external logic. It utilizes a 16-pin PDIP package.

Counter Dividers Feature Summary

• Synchronous operation eliminates output counting spikes associated with ripple-clock counters
• Parallel asynchronous load allows modification of count length for modulo-N dividers
• Look-ahead circuitry enables easy cascading of multiple counters

Counter Dividers Applications

• Binary counting applications requiring reversible direction control
• Modulo-N frequency division circuits
• Cascaded multi-stage digital counters

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'E4' corresponds to lead-free packaging requirements when sourcing. Confirm that the 16-pin PDIP tube format matches your assembly line handling capabilities. Ensure the -40°C to +85°C industrial temperature rating aligns with your system's environmental specifications before finalizing procurement.

Counter Dividers Selection Notes

Select this component when synchronous counting behavior is required to prevent glitches common in asynchronous designs. The HC series offers low power consumption suitable for battery-operated systems. Consider the 16-pin PDIP package if through-hole mounting is necessary for mechanical stability or prototyping environments.

Counter Dividers Part Context

This part belongs to the SN74HC193 family of 4-bit synchronous reversible counters. It is distinct from the SN74HC191, which lacks the separate up/down clock inputs. The NE4 designation indicates a lead-free variant of the standard SN74HC193N housed in a plastic dual-in-line package.
