Counter Dividers datasheet and documents for SNJ54HC193J
Counter Dividers Overview
The SNJ54HC193J is a military-grade, 4-bit synchronous reversible up/down binary counter manufactured by Texas Instruments. It operates within a wide supply voltage range of 2 V to 6 V and supports an operating temperature range from -55°C to 125°C. The device features fully synchronous counting with look-ahead circuitry for cascading, parallel asynchronous load capability for modulo-N division, and asynchronous clear functionality. It utilizes a 16-pin ceramic dual in-line package (CDIP-J) designed for high-reliability applications.
Counter Dividers Feature Summary
- Synchronous operation eliminates output counting spikes associated with asynchronous counters
- Look-ahead circuitry enables easy cascading without external logic
- Parallel asynchronous load allows independent presetting for modulo-N count lengths
- Asynchronous clear forces all outputs low independently of other inputs
Counter Dividers Applications
- Military and defense electronic systems requiring extended temperature tolerance
- High-reliability aerospace control circuits
- Industrial automation counters operating in extreme environments
- Cascaded multi-stage binary counting architectures
Counter Dividers Procurement Notes
Verify the specific ordering suffix 'J' corresponds to the CDIP-16 ceramic package and military grade qualification. Confirm RoHS exemption status as indicated in official documentation. Ensure compatibility with existing board layouts for the specified package dimensions and pinout configuration before finalizing procurement.
Counter Dividers Selection Notes
Select this component when military-grade reliability and extended temperature performance are required. The HC193 series offers synchronous counting to prevent glitches. Compare against SN74HC193 variants if commercial temperature ranges suffice. Verify that the 16-pin CDIP package fits the mechanical constraints of the target assembly.
Counter Dividers Part Context
This part belongs to the SN54HC193 family of 4-bit synchronous reversible counters. The 'SNJ' prefix denotes the military grade version housed in a ceramic dual in-line package. It shares functional specifications with the SN74HC193 but differs in environmental ratings and packaging materials suitable for harsh conditions.
Counter Dividers Replacement Considerations
SNJ54HC193W (CFP package), SNJ54HC193FK (LCCC package). Commercial equivalents include SN74HC193 variants which lack the extended temperature and military qualification.
