74HC9114N,112

Overview

The NXP USA Inc. 74HC9114N,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 threshold levels for TTL logic interfacing. The device includes clamp diodes on inputs to support voltages exceeding VCC when used with current-limiting resistors. It provides high noise immunity and unlimited input rise/fall times due to Schmitt trigger characteristics. The component complies with JEDEC standards JESD8C and JESD7A and offers robust latch-up performance exceeding 100 mA per JESD 78 Class II Level B.

Feature Summary

• Schmitt trigger inputs convert slowly changing signals into sharply defined jitter-free outputs
• Open-drain outputs allow flexible interfacing and wired-OR configurations
• Input clamp diodes enable safe operation with voltages exceeding the supply rail

Applications

• Signal conditioning for noisy environments
• Waveform shaping from analog or slow digital sources
• TTL-to-CMOS level translation interfaces

Procurement Notes

Verify the specific ordering code suffix matches the required package variant. Confirm RoHS compliance status as indicated in the official datasheet. Ensure the temperature grade aligns with the intended operational environment. Cross-reference the manufacturer part number against the distributor's catalog to confirm authenticity and revision level before finalizing procurement orders.

Selection Notes

Select this component when nine independent inverting buffers with hysteresis are required. The open-drain output structure necessitates external pull-up resistors for proper HIGH-level voltage definition. Consider the HC series for standard CMOS speed or HCT for direct TTL compatibility. Verify that the load capacitance requirements fall within the specified dynamic characteristic limits for the target operating frequency.

Part Context

This component belongs to the Nexperia 74HC/HCT logic family, specifically designed as a wide Schmitt trigger buffer. It serves as a signal integrity enhancement device for digital systems requiring noise rejection. The nine-channel configuration allows for parallel data bus inversion or clock signal cleaning within a single integrated circuit package.

Replacement Considerations

Direct functional equivalents include the 74HCT9114 for TTL-compatible voltage levels. Verify pinout compatibility and electrical specifications such as propagation delay and supply voltage ranges when substituting with other manufacturers' wide Schmitt trigger buffers.
