Overview

74VCX08MTCX from ON Semiconductor is a low-voltage quad 2-input AND gate IC designed for level-shifted logic interfacing 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 robust signal conditioning in portable and battery-powered digital control circuits.

For engineers reviewing the 74VCX08MTCX datasheet, pinout, applications, or equivalent options, key selection criteria include its 3.6V I/O tolerance across 1.2–3.6V supply range, power-off high-impedance behavior, quiet-series EMI reduction, and TSSOP-14 package compatibility with space-constrained PCB layouts.

Technical Context

The 74VCX08MTCX implements four independent 2-input AND gates using advanced CMOS process technology optimized for speed-power tradeoff in low-voltage operation. Its input structure enables safe interfacing between 1.2V, 1.8V, 2.5V, and 3.3V logic domains without external level shifters.

Each gate features static output drive (±24mA at 3.0V), power-off high-impedance I/Os, and latchup immunity exceeding 300mA. AC performance is specified under defined load conditions (CL = 30pF, RL = 500Ω) with skew ≤0.5ns between outputs switching in the same direction.

Key Specifications

Pinout & Package

FAQ

Is 74VCX08MTCX still in active production?

No - the 74VCX08MTCX is marked DISCONTINUED and NOT RECOMMENDED FOR NEW DESIGN per ON Semiconductor's official documentation. However, Aetrix Electronics maintains legacy inventory and offers lifecycle management support, including last-time-buy planning and cross-reference assistance for migration to functionally aligned alternatives such as SN74LVC08APW or 74AUP2G08DCUR.

What is the maximum input voltage the 74VCX08MTCX can tolerate when V_CC = 1.2V?

The 74VCX08MTCX supports 3.6V-tolerant inputs regardless of V_CC level. When V_CC = 1.2V, inputs may safely swing from –0.5V to +3.6V without damage or functional degradation - enabling direct connection to 3.3V buses while operating from ultra-low-voltage rails.

Does the 74VCX08MTCX require external pull-up or pull-down resistors on unused inputs?

Yes - per the Recommended Operating Conditions table, floating or unused inputs must be held HIGH or LOW. Leaving inputs unconnected risks increased ICC, noise susceptibility, and potential oscillation. For 74VCX08MTCX, use 10kΩ pull-up/down resistors tied to V_CC or GND to ensure stable logic states and minimize power consumption.

Can the 74VCX08MTCX drive a 50pF load at 3.3V with guaranteed timing?

The 74VCX08MTCX AC Electrical Characteristics specify t_PHL/t_PLH ≤2.8ns at V_CC = 3.3V with CL = 30pF. For CL = 50pF, the datasheet notes an approximate +300ps increase - resulting in ≤3.1ns max delay. This remains within typical high-speed digital timing budgets, but system-level validation is recommended for setup/hold-critical paths.

What does "Quiet Series™" mean for the 74VCX08MTCX?

Quiet Series™ refers to proprietary output-stage design techniques that suppress dynamic voltage transients. For the 74VCX08MTCX, this yields measured VOLP ≤0.8V and VOHV ≥2.2V at 3.3V - reducing simultaneous switching noise (SSN), lowering EMI emissions, and improving signal integrity in dense PCB layouts without added ferrite beads or RC filters.
