Overview
The SN74AHCT00NE4 is a quadruple 2-input positive-NAND gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible CMOS inputs. The device provides balanced push-pull outputs with an output drive capability of ±8 mA at 5 V. It is housed in a 14-pin PDIP package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- TTL-voltage compatible inputs for direct interfacing with standard logic devices
- Balanced CMOS push-pull outputs providing equal sourcing and sinking current capabilities
- Latch-up performance exceeding 250 mA per JESD 17 standards
Applications
- Enabling or disabling digital signals
- Controlling indicator LEDs
- Translation between communication modules and system controllers
Procurement Notes
Verify the specific ordering suffix 'E4' against the manufacturer's latest documentation to confirm compliance details and material specifications. Confirm that the PDIP-14 package matches the target PCB footprint requirements. Ensure the operating temperature range meets the environmental constraints of the final assembly.
Selection Notes
Select this component when TTL-level input compatibility is required alongside CMOS low-power characteristics. The ±8 mA drive strength is suitable for moderate capacitive loads, provided the total capacitance does not exceed recommended limits. Verify that the 4.5 V to 5.5 V supply range aligns with the system power architecture.
Part Context
This part belongs to the SNx4AHCT00 family of quadruple 2-input positive-NAND gates. The family utilizes advanced CMOS technology to achieve low power consumption while maintaining high-speed operation. The 'N' designation indicates the through-hole PDIP package variant, distinguishing it from surface-mount options like SOIC or SSOP.

FAQ
How should unused inputs be handled?
Unused inputs must be terminated to either VCC or ground to prevent undefined operational states and excessive power consumption.
What is the maximum recommended capacitive load?
The device can drive a load with a total capacitance less than or equal to 50 pF while meeting all data sheet specifications.
