74HC9114D,112

Overview

The Nexperia 74HC9114D,112 is a nine-wide Schmitt trigger buffer with open-drain inverting outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and features reduced input thresholds for TTL interfacing. The device includes clamp diodes on inputs to support voltages exceeding VCC. It provides high noise immunity and unlimited input rise/fall times due to Schmitt trigger action. Static characteristics include an input leakage current of ±1.0 μA maximum at -40 °C to +125 °C. Dynamic performance specifies propagation delays ranging from 10 ns to 33 ns depending on voltage and temperature.

Feature Summary

• Nine-channel wide Schmitt trigger buffer with inverting logic function
• Open-drain output configuration suitable for wired-OR applications
• Input clamp diodes enable interface to voltages exceeding VCC
• Reduced input threshold levels allow direct interfacing to TTL logic

Applications

• Signal conditioning for slowly changing waveforms
• TTL-to-CMOS level translation interfaces
• High-noise environment signal buffering
• Wired-logic bus configurations using open-drain outputs

Procurement Notes

Verify the specific ordering suffix '112' against the manufacturer's official documentation to confirm packaging details. Confirm RoHS compliance status and REACH registration requirements prior to procurement. Ensure the SO20 package variant matches the design footprint. Check for any end-of-life notifications or longevity program updates directly from Nexperia before finalizing component selection.

Selection Notes

Select this component when nine independent inverting buffers are required in a single package. The open-drain outputs necessitate external pull-up resistors for proper HIGH-level operation. Verify that the application voltage remains within the 2.0 V to 6.0 V recommended operating range. Consider the Schmitt trigger hysteresis if input signals exhibit significant noise or slow transition times.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. It is pin-compatible with other standard 20-pin small outline packages in the family. The device is specified for industrial temperature ranges extending up to +125 °C. It complies with JEDEC standards JESD8C and JESD7A for CMOS logic integration.

Replacement Considerations

The 74HCT9114D serves as a compatible alternative within the same product family, offering TTL-compatible input levels.
