Product details

Overview

74VCX08MTC from ON Semiconductor is a low-voltage quad 2-input AND gate IC designed for logic-level translation and signal gating in mixed-supply systems. It operates from 1.2V to 3.6V V_CC, supports 3.6V-tolerant inputs/outputs, delivers ≤2.8ns propagation delay at 3.3V, and provides ±24mA drive strength at 3.0V - enabling use in battery-powered portable interfaces and FPGA I/O bridging.

For engineers reviewing the 74VCX08MTC datasheet, pinout, applications, or equivalent options, this device serves as a voltage-flexible combinational logic element where level-shifting, low-power static drive, and power-off high-impedance behavior are required in space-constrained TSSOP-14 layouts.

Technical Context

The 74VCX08MTC implements four independent non-inverting AND gates using advanced CMOS process technology optimized for speed-power trade-offs across 1.2V–3.6V supply ranges. Its input and output structures incorporate dual-threshold protection circuitry enabling safe interfacing with higher-voltage (up to 3.6V) signals while powered from lower V_CC.

Each gate exhibits rail-to-rail output swing, power-off high-impedance I/O states, and guaranteed AC timing performance down to 1.2V operation. Input leakage remains ≤±5µA over full V_CC and temperature range, and latchup immunity exceeds 300mA per JEDEC JESD78.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.2V to 3.6V - enables direct interface with 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V logic domains without external level shifters.
t_PD Max	2.8ns at V_CC = 3.3V, CL = 30pF - supports >350MHz toggle rates in critical data-path gating applications.
I/O Voltage Tolerance	3.6V tolerant inputs and outputs - allows safe connection to 3.3V systems even when V_CC = 1.2V–2.5V.
I_OH/I_OL	±24mA at V_CC = 3.0V - drives standard TTL loads or multiple CMOS inputs without buffering.
Power-Off High-Z	Inputs and outputs enter high-impedance state when V_CC = 0V - prevents back-driving and bus contention during power sequencing.
Quiescent ICC	20µA max - minimizes standby current in always-on subsystems such as wake-up logic or sensor interface enable paths.

Pinout & Package

74VCX08MTC is housed in a 14-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153 compliant, 4.4mm wide, with 0.65mm lead pitch. Pin 1 is marked by a beveled corner or dot; the package includes exposed pad (DAP) not connected internally.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 8, 9, 11, 12	Input (A1/B1/A2/B2/A3/B3/A4/B4)	Four independent AND gate inputs; each pair (e.g., pins 1&2) feeds one gate; 3.6V-tolerant, no external pull-ups required.
3, 6, 10, 13	Output (Y1/Y2/Y3/Y4)	CMOS-compatible outputs with rail-to-rail swing; support ±24mA drive at 3.0V and retain high-Z when V_CC = 0V.
7	GND	Ground reference for all logic and I/O; must be low-inductance connection to minimize switching noise coupling.
14	V_CC	Primary power supply; decoupling capacitor (0.1µF ceramic) required within 5mm of this pin for stable high-speed operation.

Key Features

Feature	Design Value
Wide V_CC range (1.2V–3.6V)	Enables single-device compatibility across multiple voltage rails in multi-core SoC power domains or mixed-voltage PCBs.
3.6V-tolerant I/O	Eliminates need for discrete level translators when interfacing 3.3V peripherals (e.g., SDIO, UART, GPIO expanders) with sub-2V controllers.
Quiet Series™ EMI reduction	Reduces simultaneous switching noise (SSN) via controlled edge rates and internal slew limiting - critical for EMC-compliant portable designs.
Power-off high-impedance I/O	Prevents current leakage and signal corruption during hot-swap, partial power-down, or system suspend modes without external isolation switches.
Latchup immunity >300mA	Ensures robustness against transient overvoltage events and board-level ESD discharges per JEDEC JESD78 Class II.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad 2-input AND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC08APW	Same 14-pin TSSOP package; 1.65V–3.6V V_CC range; 3.6V-tolerant I/O; t_PD = 3.7ns @ 3.3V (slower than 74VCX08MTC's 2.8ns).	Lower minimum V_CC (1.65V vs. 1.2V) limits use in deep-sleep 1.2V domains; suitable for 1.8V+ systems only.	Select when TI ecosystem alignment or longer production availability is prioritized over sub-3ns speed or 1.2V operation.
74AUP1G08GW	Single-gate SOT353 package; 0.8V–3.6V V_CC; t_PD = 6.2ns @ 3.3V; requires four units for quad functionality.	Not pin-compatible; increases layout area and assembly cost; lacks integrated quad structure and shared V_CC/GND efficiency.	Choose only for ultra-low-power (90nA ICC) applications where speed and integration are secondary to nanowatt standby consumption.

Compared with SN74LVC08APW and 74AUP1G08GW, the 74VCX08MTC uniquely supports 1.2V operation with 2.8ns speed and quad integration in TSSOP-14 - making it optimal for compact, multi-rail portable systems requiring both voltage flexibility and timing precision.

FAQ

What is the minimum operating voltage for the 74VCX08MTC?

The 74VCX08MTC operates down to 1.2V V_CC, verified across –40°C to +85°C ambient temperature. At 1.2V, it delivers functional AND logic with ±100µA output drive and valid VIH/VIL thresholds per datasheet Table 2. This enables direct use in deep-sleep domains of modern microcontrollers and SoCs without level-shifting overhead.

Does the 74VCX08MTC support 3.3V I/O while powered from 1.8V?

Yes, the 74VCX08MTC supports 3.6V-tolerant inputs and outputs regardless of V_CC level - including when V_CC = 1.8V. Its input protection circuitry clamps voltages up to 4.6V absolute maximum, and output stages maintain rail-to-rail swing referenced to V_CC, allowing safe interfacing with 3.3V peripherals in mixed-voltage systems.

Is the 74VCX08MTC pin-compatible with other 74-series AND gates in TSSOP-14?

No - the 74VCX08MTC uses standard 14-pin TSSOP pinout (JEDEC MO-153) but differs electrically from non-VCX families. While pin assignments match generic quad 2-input AND logic (e.g., inputs on pins 1/2/4/5/8/9/11/12, outputs on 3/6/10/13), its 1.2V–3.6V operation, 3.6V-tolerant I/O, and Quiet Series™ noise control are unique to the VCX family and not replicated in LVC or AHC variants.

What is the propagation delay of the 74VCX08MTC at 2.5V V_CC?

At V_CC = 2.5V ±0.2V, CL = 30pF, and RL = 500Ω, the 74VCX08MTC exhibits a maximum propagation delay (t_PHL/t_PLH) of 3.7ns, as specified in the AC Electrical Characteristics table. This value includes typical process variation and ensures timing margin for 2.5V logic domains in industrial and networking equipment.

How does the power-off high-impedance feature of the 74VCX08MTC benefit system design?

The 74VCX08MTC places both inputs and outputs into high-impedance state when V_CC = 0V, preventing back-driving of powered sections during partial power-down or hot-swap events. This eliminates risk of latchup or excessive current draw in modular systems - for example, when a 74VCX08MTC-enabled sensor card is inserted into a live backplane, its I/O remains safely isolated until V_CC ramps.
