Product details

Overview

74VCX132MTC from Fairchild Semiconductor is a low-voltage quad 2-input NAND gate IC with Schmitt trigger inputs, 1.4V–3.6V V_CC operation, 3.6V-tolerant I/O, and 3.3 ns max propagation delay at 3.3V - used in noise-prone digital interface conditioning for industrial control and portable logic level translation.

For engineers reviewing the 74VCX132MTC datasheet, pinout, applications, or equivalent options, key selection factors include hysteresis voltage (0.3–1.2 V), input leakage (≤5.0 µA), output drive (±24 mA @ 3.0V), power-off high-impedance behavior, and TSSOP-14 JEDEC MO-153 package compatibility.

Technical Context

The 74VCX132MTC implements four independent NAND gates, each with asymmetric input thresholds enabling clean signal regeneration from slow-rising or noisy waveforms. Its Schmitt-trigger hysteresis (V_H = 0.3–1.2 V) eliminates chatter on marginal edges without external RC networks.

Designed for mixed-voltage systems, the device supports 1.4V–3.6V V_CC while maintaining full 3.6V tolerance on all I/O pins - allowing direct interfacing between 1.8V/2.5V logic domains and 3.3V peripherals without level shifters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.4 V to 3.6 V - enables operation across 1.8 V, 2.5 V, and 3.3 V logic families
Input Hysteresis (V_H)	0.3 V to 1.2 V - ensures reliable noise rejection and eliminates metastability on slow transitions
t_PD Max	3.3 ns @ V_CC = 3.3 V - supports >100 MHz toggle rates in critical timing paths
I/O Voltage Tolerance	Up to 3.6 V - allows safe connection to higher-voltage buses without clamping diodes or external protection
Output Drive (I_OH/I_OL)	±24 mA @ 3.0 V - drives standard TTL loads and multiple CMOS inputs directly
Power-Off High-Z	Inputs and outputs enter high-impedance state when V_CC = 0 V - prevents back-driving in hot-swap or partial-power-down systems
I_IN Leakage	≤5.0 µA @ V_I = 0–3.6 V - minimizes current draw in battery-powered standby modes

Pinout & Package

74VCX132MTC is housed in a 14-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153 compliant, 4.4 mm wide, with 0.65 mm lead pitch and exposed pad not present.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 8, 9, 12, 13	Input (A1/B1, A2/B2, A3/B3, A4/B4)	Four independent NAND gate inputs with Schmitt-trigger hysteresis; tolerate up to 3.6 V regardless of V_CC
3, 6, 10, 11	Output (Y1, Y2, Y3, Y4)	Active-low NAND outputs; 3.6 V tolerant, ±24 mA drive capability at 3.0 V V_CC
7	GND	Ground reference for all logic and power domains; required for proper hysteresis threshold referencing
14	V_CC	Primary supply rail (1.4–3.6 V); powers internal logic and defines output voltage swing and drive strength

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar NAND gate with Schmitt trigger applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC132APW	Same 14-pin TSSOP package; lower V_CC range (1.65–3.6 V); no 1.4 V operation; hysteresis ~0.3 V smaller at 1.8 V	Not suitable for sub-1.65 V systems; requires tighter V_CC regulation; slightly reduced noise margin below 2.0 V	Preferred where TI ecosystem integration or LVC family consistency is prioritized over ultra-low-voltage support
74AHC132PW	Higher V_CC range (2.0–5.5 V); no 1.4 V operation; 5 V tolerant but not 3.6 V optimized; t_PD ~4.5 ns @ 3.3 V	Cannot replace 74VCX132MTC in 1.4–1.6 V designs; less optimal for battery-critical low-V_CC operation	Chosen when legacy 5 V compatibility or higher drive at 5 V is required, and 1.4 V operation is unnecessary

Compared with SN74LVC132APW and 74AHC132PW, the 74VCX132MTC uniquely supports 1.4 V operation with guaranteed hysteresis and 3.6 V I/O tolerance - making it the only option for dual-role systems requiring both ultra-low-power sleep states and 3.3 V peripheral interoperability.

FAQ

What is the minimum operating voltage for the 74VCX132MTC?

The 74VCX132MTC operates down to 1.4 V V_CC, with guaranteed functionality including Schmitt-trigger hysteresis, 3.6 V I/O tolerance, and output drive specifications across the full 1.4–3.6 V range - verified per DC Electrical Characteristics tables in Fairchild DS500164.

Does the 74VCX132MTC support hot insertion or partial power-down?

Yes, the 74VCX132MTC features power-off high-impedance inputs and outputs, meaning both pins enter a high-Z state when V_CC = 0 V - preventing back-current flow and bus contention during hot-swap or staged power-up/down sequences in modular systems.

Can the 74VCX132MTC safely interface a 1.8 V microcontroller with a 3.3 V display driver?

Yes - the 74VCX132MTC accepts 1.8 V logic inputs while powered at 1.8 V, and its outputs swing rail-to-rail up to 3.3 V when V_CC = 3.3 V; its 3.6 V-tolerant I/O allows direct connection without level shifters or resistive dividers.

What is the typical input hysteresis voltage of the 74VCX132MTC at 2.5 V V_CC?

At 2.5 V V_CC, the 74VCX132MTC exhibits an input hysteresis (V_H) of 0.3 V to 1.0 V, as specified in the DC Electrical Characteristics table - enabling reliable noise rejection on signals with ≤100 mV peak-to-peak interference.

Is the 74VCX132MTC RoHS-compliant and lead-free?

Yes, the 74VCX132MTC in TSSOP package (MTC14) is lead-free and complies with RoHS Directive 2011/65/EU; Fairchild confirmed Pb-free construction per JEDEC J-STD-020B, with compatible reflow profiles for standard SMT assembly.
