Product details

Overview

74VCX00MTC from ON Semiconductor is a low-voltage quad 2-input NAND gate IC designed for logic-level translation and signal conditioning in mixed-supply systems. It operates from 1.2V to 3.6V V_CC, supports 3.6V-tolerant I/O, delivers ±24mA output drive at 3.0V, and achieves 2.8ns max propagation delay (V_CC = 3.0–3.6V). It is used in portable battery-powered interfaces requiring level-shifting between 1.2V/1.8V/2.5V and 3.3V domains.

For engineers reviewing the 74VCX00MTC datasheet, pinout, applications, or equivalent options, key selection criteria include its 3.6V-tolerant I/O capability across wide V_CC range, power-off high-impedance behavior, static drive strength, latchup immunity per JEDEC 78, and TSSOP-14 package compatibility with space-constrained PCB layouts.

Technical Context

The 74VCX00MTC implements four independent 2-input NAND gates using advanced CMOS process technology optimized for speed-power tradeoff in sub-3.6V applications. Its input structure enables operation with V_CC as low as 1.2V while accepting up to 3.6V logic signals without external level shifters.

All inputs and outputs are 3.6V-tolerant regardless of V_CC setting, and both inputs and outputs enter high-impedance state when V_CC = 0V - enabling safe hot-insertion and bus isolation. Propagation delay varies predictably with supply voltage and load: 2.8ns (max) at 3.3V/30pF, increasing to 37.0ns at 1.2V/15pF.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.2V to 3.6V - Enables direct interface between 1.2V, 1.8V, 2.5V, and 3.3V logic domains without external translators.
I/O Voltage Tolerance	Up to 3.6V - Inputs and outputs withstand 3.6V signals even when V_CC = 1.2V, eliminating need for clamping diodes.
t_PD (Max)	2.8ns at V_CC = 3.0–3.6V, CL = 30pF - Supports >300MHz toggle rates in critical timing paths.
I_OH/I_OL	±24mA at V_CC = 3.0V - Drives standard TTL loads or multiple CMOS inputs without buffering.
Power-Off Behavior	High-impedance I/O when V_CC = 0V - Prevents back-driving and ensures safe insertion into live backplanes or hot-swap systems.
Latchup Immunity	Exceeds JEDEC 78 - Guarantees robustness against transient-induced latchup in noisy industrial environments.
ESD Rating	HBM > 2000V, MM > 250V - Meets standard reliability requirements for handling and assembly without special ESD controls.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad NAND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC00APWR	1.65–3.6V V_CC; no 1.2V operation; 3.6V-tolerant I/O; 2.5ns t_PD (3.3V); same TSSOP-14 footprint.	Not suitable for 1.2V/1.4V systems; better performance above 1.65V; higher drive (±24mA @ 3.3V) matches 74VCX00MTC.	Select when design uses ≥1.65V supply and requires marginally faster timing; verify layout compatibility with MTC14 land pattern.
74ALVC00MTCX	1.65–3.6V V_CC; 3.6V-tolerant I/O; 2.1ns t_PD (3.3V); lower ICC (10µA typical); same TSSOP-14 package.	Higher speed and lower quiescent current, but lacks 1.2V–1.4V support; not recommended for ultra-low-voltage battery backup circuits.	Choose for high-speed, low-power 1.8V/2.5V/3.3V-only designs where sub-2.5ns delay is critical and 1.2V operation is unnecessary.

Compared with SN74LVC00APWR and 74ALVC00MTCX, the 74VCX00MTC uniquely supports 1.2V operation and retains full 3.6V I/O tolerance - making it the only option among the three for dual-domain systems spanning 1.2V logic and 3.3V peripherals without additional voltage translation.

FAQ

What is the minimum operating V_CC for 74VCX00MTC?

The 74VCX00MTC supports operation down to 1.2V V_CC, with verified DC and AC performance including VIH/VIL thresholds, output drive (±100µA at 1.2V), and propagation delay (37.0ns max at 1.2V/15pF). This enables use in ultra-low-power subsystems such as battery-backed real-time clocks or sleep-mode controllers where other LVC-family devices fail to operate.

Does 74VCX00MTC support hot-plug or power-off isolation?

Yes - the 74VCX00MTC enters high-impedance state on all inputs and outputs when V_CC = 0V, preventing back-driving of powered circuitry and enabling safe insertion into live backplanes or hot-swap modules. This behavior is explicitly characterized in the datasheet under "Power-off high impedance inputs and outputs" and confirmed across –40°C to +85°C.

Is the 74VCX00MTC pin-compatible with standard 74-series TSSOP NAND gates?

Yes - the 74VCX00MTC uses standard 14-pin TSSOP pinout (MTC14) matching JEDEC MO-153, identical to industry-standard 74LVC00 and 74ALVC00 in TSSOP-14. Pin assignments for inputs (A1/B1…), outputs (Y1…), V_CC, and GND are fully aligned, allowing drop-in replacement where voltage and timing requirements match.

What is the maximum capacitive load the 74VCX00MTC can drive at 3.3V?

At V_CC = 3.3V, the 74VCX00MTC is characterized for CL = 30pF (t_PD ≤ 2.8ns) and CL = 15pF (t_PD ≤ 14.8ns). While not explicitly rated beyond 30pF, its ±24mA output drive supports heavier loads - e.g., driving two 50Ω transmission lines (≈20pF each) or fanout to ≥10 standard CMOS inputs (typical C_IN = 6pF) without timing violation.

Why is 74VCX00MTC marked "Not Recommended for New Design"?

ON Semiconductor discontinued the 74VCX00MTC as part of portfolio rationalization; it remains available for legacy support and existing production but is not promoted for new designs. Customers designing new products should evaluate alternatives like SN74LVC00APWR or 74ALVC00MTCX - though 74VCX00MTC retains unique 1.2V–3.6V operation that those parts do not offer.
