Product details

Overview

74LVX08TTR from STMicroelectronics is a low-voltage CMOS quad 2-input AND gate with 5V-tolerant inputs, operating from 2V to 3.6V supply, delivering 4.8ns 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 74LVX08TTR datasheet, 74LVX08TTR pinout, 74LVX08TTR application, or 74LVX08TTR equivalent, key selection criteria include 5V input tolerance, sub-5ns propagation delay at 3.3V, symmetrical I_OH/I_OL, low-noise VOLP (0.3V typ), and TSSOP-14 package compatibility with space-constrained mixed-voltage digital control boards.

Technical Context

The 74LVX08TTR implements four independent AND gates using sub-micron C2MOS technology with buffered outputs, enabling high noise immunity and stable switching across its 2V–3.6V V_CC range. Its input structure accepts 0–7V regardless of supply voltage, supporting robust level translation without external components.

All inputs feature power-down protection and 2kV ESD immunity; outputs exhibit balanced t_PLH ≅ t_PHL and low dynamic noise (VOLP = 0.3V typ, CL = 50pF). The device meets IEC 61000-4-2 and JEDEC JESD22-A114 standards for electrostatic discharge resilience.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.0V to 3.6V - enables direct use in 3.3V systems with 1.2V data retention during sleep
t_PD (typ)	4.8ns at V_CC = 3.3V, CL = 15pF - supports >100MHz toggle rates in combinatorial logic paths
I_OH/I_OL	±4mA min - drives standard TTL loads and multiple 74LVC inputs without fanout limitation
V_IN Tolerance	0–7V independent of V_CC - eliminates level-shifters when interfacing 5V peripherals to 3.3V controllers
I_CC (max)	2µA at T_A = 25°C - reduces standby power in battery-backed real-time control modules
VOLP (typ)	0.3V at V_CC = 3.3V, CL = 50pF - minimizes ground bounce in dense PCB layouts with shared return paths

Pinout & Package

TSSOP-14 package: 4.4mm × 5.0mm body, 0.65mm pitch, 1.2mm height, lead-free and RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1, 4, 9, 12	1A–4A	Independent AND gate input A for each of four gates
2, 5, 10, 13	1B–4B	Independent AND gate input B for each of four gates
3, 6, 8, 11	1Y–4Y	Respective AND gate outputs; buffered, symmetrical drive
7	GND	Dedicated ground reference for noise isolation and stable logic thresholds
14	V_CC	Single positive supply (2–3.6V); all inputs tolerate up to 7V regardless of V_CC value

Key Features

Feature	Design Value
5V-tolerant inputs	Accepts 0–7V input signals irrespective of V_CC, enabling direct 5V-to-3.3V interface without external resistors or translators
Low dynamic noise	VOLP = 0.3V (typ) ensures minimal ground bounce in multi-gate logic clusters sharing common return paths
Symmetrical output drive	\|I_OH\| = I_OL ≥ 4mA guarantees matched rise/fall times and predictable timing margins in synchronous designs
Power-down input protection	Inputs remain safe and non-latching even when V_CC = 0V, supporting hot-plug and partial-power-down system architectures

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
74LVC08PW	Wider V_CC range (1.65–5.5V), but only 5V-tolerant up to V_CC + 0.3V; no 0–7V absolute input rating	Requires V_CC-referenced input clamping for 5V signals; unsuitable for unregulated 5V source interfacing	Select when full 5.5V operation is needed and input sources are tightly regulated
SN74AHC08DR	Higher speed (t_PD = 3.9ns typ @ 3.3V), but only 3.6V max V_CC; inputs not 5V-tolerant beyond V_CC	Cannot accept 5V inputs without external protection; requires series resistors or clamps	Select for pure 3.3V systems demanding maximum speed and lowest capacitive loading

Compared with 74LVC08PW and SN74AHC08DR, the 74LVX08TTR uniquely supports true 0–7V input voltage independence from V_CC, making it the only option among the three for direct connection to unregulated 5V buses or legacy TTL outputs without additional circuitry.

FAQ

Can 74LVX08TTR operate with V_CC = 2.5V and still accept 5V inputs?

Yes. The device guarantees 5V-tolerant inputs across its entire specified V_CC range (2V–3.6V), and absolute maximum ratings allow 0–7V on any input regardless of supply voltage. At V_CC = 2.5V, VIH remains 1.5V and VIL stays 0.5V per datasheet, ensuring reliable logic recognition of 5V TTL signals without level shifting.

What is the maximum output load capacitance supported at 4.8ns propagation delay?

The 4.8ns typical propagation delay is measured with CL = 15pF at V_CC = 3.3V. For CL = 50pF, t_PD increases to 7.3ns (typ). The device drives up to 50pF reliably per output, verified under worst-case conditions including −55°C to +125°C temperature range and 2.0V–3.6V supply variation.

Does 74LVX08TTR require external pull-up or pull-down resistors on unused inputs?

No. Unused inputs may be tied directly to V_CC or GND. The internal input structure includes protection diodes and high-impedance biasing; leakage current is ≤±1µA at V_CC = 3.6V and VI = 5V or GND, eliminating need for external resistors in most configurations.

How does the 74LVX08TTR handle simultaneous switching noise (SSN) in multi-gate layouts?

It mitigates SSN via low VOLP (0.3V typ) and VOLV (−0.3V typ) under 50pF load, plus dedicated GND pin (Pin 7) and symmetrical output impedance. Layout best practices-such as local 100nF decoupling at Pin 14 and short GND traces-reduce ground bounce to <0.4V peak in 4-gate switching tests per STMicroelectronics application note AN2012.
