74ALVC132MTCX

Overview

The 74ALVC132MTCX is a quad 2-input NAND gate with Schmitt trigger inputs, manufactured by Fairchild Semiconductor. It utilizes advanced ALVC CMOS technology to deliver high-speed operation while maintaining low power dissipation. The device operates within a supply voltage range of 1.65V to 3.6V and features open-drain outputs. It is housed in a 14-pin TSSOP package (JEDEC MO-153) with a width of 4.40mm. Key electrical parameters include a propagation delay of 3ns at VCC=3.3V, low-level output current of 24mA, and high-level output current of -24mA. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Schmitt trigger inputs provide noise filtering and hysteresis for clean signal transitions.
• Open-drain output configuration allows for flexible interfacing and wired-OR logic applications.
• Advanced ALVC CMOS technology ensures high-speed performance with minimal power consumption.

Applications

• High-speed digital signal processing circuits requiring noise immunity
• Microcontroller interface logic for level shifting and buffering
• General-purpose logic gating in portable battery-powered devices

Procurement Notes

Verify the manufacturer marking on the component body to confirm Fairchild or onsemi origin, as ownership transferred. Ensure the 14-TSSOP package matches your PCB footprint dimensions precisely. Check for RoHS compliance markings if environmental regulations apply to your assembly process. Confirm that the open-drain output requirement aligns with your system design, as pull-up resistors are necessary for proper high-state logic levels.

Selection Notes

Select this component when Schmitt trigger action is required to mitigate signal noise on NAND gate inputs. The open-drain output necessitates external pull-up resistors; ensure these are included in the schematic design. Compare propagation delay specifications against system timing requirements to verify compatibility. Consider the 1.65V minimum supply voltage if designing for ultra-low-power applications compared to standard 3.3V-only logic families.

Part Context

This part belongs to the 74ALVC series, which represents a high-performance subset of low-voltage CMOS logic. The ALVC family bridges the gap between speed and power efficiency, offering faster switching than standard LVC parts while consuming less power than older HCT/HCU technologies. The MTCX suffix indicates the specific 14-pin TSSOP surface-mount packaging variant distributed by Fairchild Semiconductor.

Replacement Considerations

Direct pin-compatible substitutes may include other manufacturers' 74ALVC132 variants in 14-TSSOP packages. Verify that replacement parts maintain the same Schmitt trigger input characteristics and open-drain output structure. Cross-reference electrical parameters such as propagation delay and output drive current to ensure functional equivalence in the target application.
