74HCT14S14-13

Overview

The 74HCT14S14-13 is a hex inverter with Schmitt trigger inputs manufactured by Diodes Incorporated. It operates within a supply voltage range of 4.5V to 5.5V and features standard push-pull outputs. The device provides six independent inverters, each with TTL voltage level compatible inputs. Key electrical characteristics include a maximum propagation delay of 20ns at 4.5V with a 50pF load, and output current capabilities of 4mA sourcing or sinking at VCC = 4.5V. It is housed in an SO-14 surface mount package.

Feature Summary

• Schmitt trigger action at all inputs for noise immunity
• TTL voltage level compatible inputs
• CMOS low power consumption
• ESD protection exceeding JESD 22 standards

Applications

• General purpose logic
• PCs and networking equipment
• Computer peripherals and hard drives
• TV, DVD, and set top boxes

Procurement Notes

Verify the specific suffix -13 indicates tape and reel packaging containing 2500 units per reel. Confirm the S14 designation corresponds to the SO-14 package type. Ensure compliance requirements such as RoHS and halogen-free status are documented in the official datasheet before procurement.

Selection Notes

Select this component when TTL-compatible logic levels are required with CMOS flexibility. The Schmitt trigger inputs provide necessary hysteresis for noisy environments. Verify that the 4.5V to 5.5V operating range aligns with the system power supply constraints.

Part Context

This part belongs to the 74HCT series of high-speed CMOS logic devices. It is pin-compatible with Low Power Schottky (LSTTL) logic families, facilitating direct replacement in legacy designs. The device is designed for operation with a power supply range of 4.5V to 5.5V.

Replacement Considerations

Pin-compatible alternatives exist within the LSTTL family. Verify functional equivalence regarding input thresholds and output drive currents when substituting.
