74HCT32T14-13

Inverter Gates Overview

The 74HCT32T14-13 is a quadruple 2-input OR gate manufactured by Diodes Incorporated. It operates within a supply voltage range of 4.5V to 5.5V and features standard push-pull outputs capable of sinking or sourcing 4mA at VCC = 4.5V. The device utilizes CMOS technology for low power consumption while maintaining TTL voltage level compatibility. It includes Schmitt trigger action at all inputs and provides ESD protection exceeding JESD 22 standards, including 2000-V Human Body Model and 1000-V Charged Device Model ratings. Propagation delay is specified at 24ns maximum under typical conditions.

Inverter Gates Procurement Notes

Verify the specific package code T14 corresponds to the required TSSOP-14 footprint during procurement. Confirm that the -13 suffix indicates tape and reel packaging suitable for automated assembly processes. Ensure the operating environment remains within the specified temperature range of -40°C to +125°C. Validate input voltage levels against the 4.5V to 5.5V supply requirement to maintain proper logic thresholds.

Inverter Gates Selection Notes

Select this component when TTL voltage level compatibility is required alongside CMOS low power consumption characteristics. The inclusion of Schmitt triggers makes it suitable for noisy environments requiring clean signal transitions. Verify that the 4mA output drive capability meets the load requirements of the connected circuitry. Consider the TSSOP-14 package dimensions if space constraints dictate a surface-mount solution over through-hole alternatives.

Inverter Gates Part Context

This part belongs to the 74HCT series of logic integrated circuits produced by Diodes Incorporated. The HCT designation indicates High-speed CMOS technology compatible with TTL logic levels. The base model 74HCT32 defines the logical function as a quadruple 2-input OR gate. The T14 suffix specifies the physical package type as TSSOP-14, distinguishing it from other available package options like SO-14.

Inverter Gates Replacement Considerations

Direct substitutes include the 74HCT32S14-13, which shares identical electrical specifications but utilizes an SO-14 package instead of TSSOP-14. Cross-manufacturer equivalents such as Nexperia's 74HCT32PW,118 offer similar functionality in a TSSOP-14 format. Verify pinout compatibility and package dimensions before substituting to ensure mechanical fit on the printed circuit board.

Inverter Gates FAQ

What is the Boolean function performed by the 74HCT32T14-13?

The device performs the positive Boolean function Y = A + B, representing a standard OR operation for each of its four independent channels.

How does the device handle unused inputs?

Unused inputs should be held at either VCC or Ground to prevent undefined states and excessive current consumption, as recommended in the operating conditions.

What are the ESD protection ratings for this component?

The component exceeds JESD 22 standards with 2000-V Human Body Model, 1000-V Charged Device Model, and 200-V Machine Model ESD protection ratings.
