SN74LS122N

Overview

The SN74LS122N is a single-retriggerable monostable multivibrator manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features a propagation delay of 28 ns. The device utilizes a 14-pin PDIP package designed for through-hole mounting. It supports an operating temperature range from 0°C to 70°C and provides standard TTL output current capabilities.

Feature Summary

• Retriggerable monostable multivibrator functionality
• Single circuit configuration
• Through-hole PDIP-14 packaging

Applications

• Pulse generation circuits
• Timing delays
• Waveform shaping

Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-14 through-hole package variant. Confirm RoHS compliance status as datasheets may vary by production batch. Ensure the application environment remains within the specified 0°C to 70°C temperature limits for reliable operation.

Selection Notes

Select this component when a single retriggerable monostable timer is required in a through-hole design. Compare against the SN74LS123 if dual channels are needed. Verify that the 28 ns propagation delay meets the system timing requirements.

Part Context

Part of the Texas Instruments 74LS series logic family, known for low-power Schottky performance. This monostable multivibrator complements other 74LS logic gates for complete digital system implementations.

Replacement Considerations

SN74LS122DR is listed as a manufacturer-recommended surface-mount alternative.
