74LCX32FT(AJ)

Inverter Gates Overview

The Toshiba 74LCX32FT(AJ) is a CMOS digital integrated circuit containing four independent 2-input OR gates. It operates within a supply voltage range of 1.65 V to 3.6 V and features 5-V tolerant inputs and outputs. The device achieves a maximum propagation delay of 6.5 ns at 3.3 V, with balanced output sink and source currents of 24 mA. It supports an operating temperature range from -40 °C to +125 °C and includes power-down protection on all pins. The component is housed in a TSSOP-14 package.

Inverter Gates Feature Summary

• Provides high-speed logic operation while maintaining low power dissipation characteristics typical of CMOS technology.
• Features 5-V tolerant inputs and outputs, enabling safe interfacing between low-voltage devices and 5-V supply environments.
• Includes built-in protection circuits against static discharge on all input pins.
• Offers power-down protection on all inputs and outputs to prevent damaging current backflow during partial power-down applications.

Inverter Gates Applications

• Low-voltage (3.3 V) system logic implementation
• Mixed voltage environment signal routing
• Partial power-down mode circuitry

Inverter Gates Procurement Notes

Verify the specific ordering suffix matches the required packaging format, as variations exist for tape and reel quantities. Confirm compliance with AEC-Q100 reliability standards if automotive qualification is necessary by contacting the manufacturer directly. Ensure the design accounts for the specified derating factors for power dissipation when operating above 85 °C ambient temperature.

Inverter Gates Selection Notes

Select this component for designs requiring quad 2-input OR functionality in space-constrained surface-mount layouts. It is suitable for systems needing interface capability with 5-V TTL or LVTTL logic despite lower supply voltages. Consider the 6.5 ns propagation delay limit for timing-critical paths and verify that the 24 mA drive capability meets the load requirements of the destination circuits.
