Product details

Overview

74LVX00TTR from STMicroelectronics is a low-voltage CMOS quad 2-input NAND gate with 5V-tolerant inputs, operating from 2V to 3.6V supply, delivering 4.1ns typical propagation delay at 3.3V, ±4mA symmetrical output drive, and 2µA max quiescent current - deployed in 3.3V logic interfacing between 5V and 3V systems.

For engineers reviewing the 74LVX00TTR datasheet, 74LVX00TTR pinout, 74LVX00TTR application, or 74LVX00TTR equivalent, key selection criteria include 5V input tolerance, sub-5ns propagation delay at 3.3V, I_OH/I_OL symmetry, ESD immunity (2kV), and TSSOP-14 package compatibility with space-constrained mixed-voltage digital control boards.

Technical Context

This device implements four independent NAND gates using sub-micron C2MOS technology with buffered outputs, providing high noise immunity and stable switching across its 2V–3.6V operating range. Input protection enables safe operation with 0–7V input voltages regardless of V_CC, enabling robust level translation.

Dynamic performance is characterized by balanced t_PLH ≅ t_PHL, low output ground bounce (V_OLP = 0.3V typ.), and tightly controlled skew (<1.0ns max) under 50pF load - critical for synchronous multi-gate timing integrity in clock distribution and enable logic.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.0V to 3.6V - supports battery-powered 3.3V systems with 1.2V data retention during sleep
t_PD (typ)	4.1ns at V_CC = 3.3V, CL = 15pF - enables sub-200MHz gate-level timing in combinatorial logic paths
I_OH/I_OL	±4mA min - ensures reliable driving of multiple 3.3V CMOS loads without external buffering
V_IL/V_IH	0.8V / 2.0V at V_CC = 3.0V - defines clean TTL- and 5V-compatible logic thresholds
Input Voltage Range	0V to 7V - allows direct connection to 5V signals without level shifters or clamping diodes
ESD Immunity	2kV HBM - protects against handling damage in automated assembly and field-replaceable modules

Pinout & Package

TSSOP-14 package: 4.4mm × 5.0mm body, 0.65mm pitch, 1.05mm max height, lead-free and RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1, 4, 9, 12	1A–4A	Independent NAND gate input A for each of four gates
2, 5, 10, 13	1B–4B	Independent NAND gate input B for each of four gates
3, 6, 8, 11	1Y–4Y	Respective NAND gate outputs - buffered, low-noise, symmetrical drive
7	GND	Dedicated ground reference for all internal logic and I/O structures
14	V_CC	Single positive supply for entire quad gate array - no separate I/O or core rails

Key Features

Feature	Design Value
5V-tolerant inputs	Accepts 0–7V inputs irrespective of V_CC, eliminating external level-shifting components in mixed-voltage designs
Low dynamic noise	V_OLP = 0.3V (typ) at V_CC = 3.3V - reduces ground bounce and crosstalk in dense PCB layouts
Symmetrical output drive	\|I_OH\| = I_OL ≥ 4mA - ensures matched rise/fall times and predictable timing margins
Power-down input protection	Inputs remain high-impedance and non-latching when V_CC = 0V - prevents backfeeding and bus contention

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC00APWR	Lower V_CC min (1.65V), higher I_OL (24mA), no 7V input tolerance	Requires strict 3.3V-only input sources; unsuitable for direct 5V interface	Prefer when system uses only 3.3V peripherals and demands higher drive strength
74AHC00PW	Wider V_CC range (2–5.5V), but only 5.5V input tolerant; higher ICC (10µA typ)	Lacks 7V input safety margin; less suitable for hot-plug or noisy industrial environments	Choose when operating up to 5V V_CC and 5.5V inputs suffice

Compared with SN74LVC00APWR and 74AHC00PW, the 74LVX00TTR uniquely combines 7V input tolerance with sub-5ns delay and µA-level quiescent current - making it optimal for battery-powered, mixed-voltage industrial interfaces where reliability and power efficiency are co-prioritized.

FAQ

Can 74LVX00TTR operate with V_CC = 1.8V?

No. The recommended operating V_CC range is 2.0V to 3.6V per datasheet Table 5. At 1.8V, DC parameters including V_OH, V_OL, and noise margins fall outside specification, and propagation delay increases significantly beyond guaranteed limits.

Is the 74LVX00TTR pin-compatible with standard 74LS00?

Yes - it is functionally and physically pin-compatible with the 74LS00 in TSSOP-14, but operates at lower voltage (2–3.6V vs. 4.75–5.25V) and offers 5V-tolerant inputs, unlike LS logic. No redesign is needed for drop-in replacement in existing footprints, provided supply voltage is adjusted.

What is the maximum capacitive load this device can drive reliably?

The device is characterized up to 50pF load (Table 7), with t_PD = 9.7ns (max) at V_CC = 3.3V. Driving >50pF increases delay nonlinearly and may degrade VOLP/VOLV noise margins; for heavier loads, add a buffer stage or use higher-drive variants like 74LVC00.

Does 74LVX00TTR support partial power-down (V_CC = 0V) while inputs remain active?

Yes - its inputs feature power-down protection: when V_CC = 0V, inputs present high impedance and tolerate 0–7V without backfeeding or latch-up. This enables safe "live insertion" into powered-backplane systems and hot-swap I/O modules.
