Product details
Overview
74VHCT00AMTC from onsemi is a quad 2-input NAND gate in TSSOP-14 package, designed for high-speed 5 V CMOS logic interfacing. It delivers 5.0 ns typical propagation delay, supports 4.5–5.5 V supply, and features ±25 mA output drive, input protection up to 5.5 V independent of VCC, and pin/function compatibility with 74HCT00. It enables robust level-shifting between 3 V and 5 V systems.
For engineers reviewing the 74VHCT00AMTC datasheet, pinout, applications, or equivalent options, key selection criteria include propagation delay under 7 ns at 50 pF load, noise immunity (VIH = 2.0 V, VIL = 0.8 V), power-down protection on all I/O, low ICC (≤2 µA), and TSSOP-14 footprint compatibility with legacy HCT designs.
Technical Context
The 74VHCT00AMTC implements four independent NAND gates using silicon-gate CMOS technology, with three-stage internal buffering to ensure stable output and high noise immunity. Its input protection circuitry allows safe operation when inputs are driven from 0 V to 5.5 V regardless of VCC state - critical for mixed-voltage or battery-backup systems.
All inputs and outputs feature power-down protection, enabling hot insertion and safe operation during power sequencing. The device operates across −40°C to +85°C and maintains specified VOH ≥3.94 V and VOL ≤0.36 V at 8 mA load, ensuring reliable TTL-compatible interfacing in industrial control and digital logic subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 5.0 ns typical at VCC = 5.0 V, CL = 15 pF - ensures sub-10 ns timing in synchronous logic paths |
| Supply Voltage Range | 4.5 V to 5.5 V - compatible with regulated 5 V rails and tolerant of ripple or droop |
| Input Voltage Range | −0.5 V to 5.5 V independent of VCC - enables safe interfacing with unpowered or 3 V sources |
| Output Drive | ±8 mA at VOH/VOL limits - sufficient to drive multiple 74-series TTL inputs or one HCT fanout |
| Quiescent ICC | ≤2.0 µA max at TA = 25°C - supports ultra-low static power in always-on logic blocks |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade embedded and automation applications |
| ESD Rating | 2000 V HBM - meets standard handling requirements without additional board-level protection |
Pinout & Package
TSSOP-14 WB (Case 948G), 4.9 mm × 4.4 mm body, 0.65 mm pitch, Pb-free, RoHS-compliant surface-mount package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 12, 13 | A0/B0, A1/B1, A2/B2, A3/B3 | Four independent NAND input pairs - each pair drives one gate; unused inputs must be tied HIGH/LOW |
| 3, 6, 10, 11 | O0, O1, O2, O3 | Active-high NAND outputs - open-drain behavior not supported; outputs fully buffered |
| 7 | GND | Ground reference for logic and power - requires low-inductance connection to minimize switching noise |
| 14 | VCC | Positive supply rail - decoupling capacitor (0.1 µF) required adjacent to pin for stable AC performance |
Key Features
| Feature | Design Value |
|---|---|
| High-speed CMOS architecture | 5.0 ns typical tPD matches bipolar TTL speed while retaining CMOS power efficiency |
| Input overvoltage tolerance | Inputs withstand −0.5 V to 5.5 V regardless of VCC - eliminates need for external clamping in mixed-supply systems |
| Power-down I/O protection | All pins remain protected when VCC = 0 V - enables hot-swap and battery-backup operation without latch-up risk |
| Noise-immune thresholds | VIH = 2.0 V and VIL = 0.8 V provide 1.2 V noise margin - prevents false triggering in electrically noisy environments |
| Pb-free & RoHS compliance | Meets global environmental regulations and reflow profile requirements for lead-free assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT00PW,118 | Same logic function and pinout; slightly higher ICC (4 µA max) and slower tPD (15 ns typ) | Lower speed margin; less suitable for >10 MHz clocked logic paths | Select when cost sensitivity outweighs speed requirement and legacy stock exists |
| SN74LVC00APW | 3.3 V only (1.65–3.6 V); 3.5 ns tPD; no 5 V input tolerance | Not interoperable with 5 V systems; requires level shifters for mixed-voltage use | Choose only for pure 3.3 V designs where lower voltage and faster speed are prioritized |
Compared with 74HCT00PW,118 and SN74LVC00APW, the 74VHCT00AMTC uniquely balances 5 V operation, 5 ns speed, and 5.5 V input tolerance - making it the only option among the three that safely bridges 3 V and 5 V domains without external components.

FAQ
What is the maximum operating frequency supported by the 74VHCT00AMTC?
The 74VHCT00AMTC does not specify a maximum clock frequency in its datasheet because it is a combinational logic device without an internal clock. Its usable toggle rate depends on propagation delay and system loading: with 5.0 ns typical tPD and 15 pF load, it supports clean signal transitions up to approximately 100 MHz in well-designed PCB layouts. Real-world frequency limits are determined by board parasitics, fanout, and supply decoupling - not an intrinsic device parameter.
Can the 74VHCT00AMTC be used with a 3.3 V supply?
No, the 74VHCT00AMTC is not rated for 3.3 V operation. Its recommended VCC range is strictly 4.5 V to 5.5 V per the datasheet. Supplying 3.3 V may result in undefined logic levels, excessive propagation delay, or failure to meet VIH/VIL thresholds. For 3.3 V systems, consider the SN74LVC00A or 74LVX00 - but note these lack 5 V input tolerance unlike the 74VHCT00AMTC.
Does the 74VHCT00AMTC support hot-plug or live-insertion scenarios?
Yes, the 74VHCT00AMTC supports hot-plug operation due to its power-down protection circuitry. When VCC = 0 V, inputs and outputs tolerate −0.5 V to 5.5 V without damage or latch-up. This allows safe connection to powered buses or backplane signals before main power is applied - a key requirement in modular instrumentation and telecom line cards using the 74VHCT00AMTC.
What is the meaning of "TSSOP−14 WB" in the 74VHCT00AMTC package designation?
"TSSOP−14 WB" denotes a Thin Shrink Small Outline Package with 14 leads and wide body (WB). Per onsemi's case 948G specification, it measures 4.9 mm × 4.4 mm with 0.65 mm lead pitch. The "WB" distinguishes it from narrower variants and ensures adequate creepage/clearance for industrial 5 V logic. This package is surface-mount compatible with standard reflow profiles and provides better thermal performance than SOIC-14 for the 74VHCT00AMTC.
How does the 74VHCT00AMTC differ from the standard 74HCT00 in practical design?
The 74VHCT00AMTC offers identical pinout and logic function to the 74HCT00 but improves speed (5.0 ns vs. 15 ns typical tPD) and reduces quiescent current (2 µA vs. 4 µA max). It also features enhanced input protection - allowing 5.5 V inputs even when VCC is off - whereas the 74HCT00 lacks full power-down I/O protection. These differences make the 74VHCT00AMTC preferable in high-speed, mixed-supply, or hot-swap-sensitive designs.
