MM74C193N

Counter Dividers Overview

The MM74C193N is a synchronous 4-bit up/down binary counter manufactured by onsemi. It operates within a supply voltage range of 3V to 15V and supports an operating temperature range of -55°C to +125°C. The device features asynchronous clear, preset inputs, and dedicated carry/borrow outputs for cascading. Propagation delay ranges from 100ns to 400ns depending on voltage. Maximum count frequency reaches 10MHz at 10V. It utilizes a 16-lead Plastic Dual-In-Line (PDIP) package.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with separate up and down clock inputs
• Asynchronous clear and parallel load capabilities
• Carry and borrow outputs enable direct N-bit cascading without external logic
• High noise immunity with guaranteed margins across the supply voltage range

Counter Dividers Applications

• Digital timing sequences
• Frequency division circuits
• Event counters
• Multi-stage digital systems requiring cascaded counting

Counter Dividers Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete or sourced from third-party distributors. Confirm RoHS compliance status and specific manufacturing date codes against current project requirements. Ensure the 16-PDIP package matches the target PCB footprint and verify that the CMOS technology meets the system's power consumption constraints.

Counter Dividers Selection Notes

Select the MM74C193N when a synchronous binary counter is required rather than the decade variant (MM74C192). This component is suitable for designs needing independent up/down control and cascading capability. Consider the wide supply voltage range and high noise immunity for robust operation in varying electrical environments compared to standard TTL logic families.

Counter Dividers Part Context

This component belongs to the MM74C series of monolithic complementary MOS integrated circuits. It functions as a binary counterpart to the MM74C192 decade counter. Both devices share similar pinouts and operational characteristics but differ in their counting modulus. The MM74C193 specifically handles binary sequences from zero to fifteen.

Counter Dividers Replacement Considerations

The MM74C192 serves as a functional alternative if decimal (BCD) counting is acceptable instead of binary. Other manufacturers producing equivalent 74C193 parts should be verified for pin compatibility and electrical specifications before substitution.
