STMicroelectronics 74VHC08MTR

Overview

74VHC08MTR from STMicroelectronics is a quad 2-input AND gate in high-speed CMOS technology, operating from 2V to 5.5V supply, with typical propagation delay of 4.3 ns at 5V, symmetrical output drive (±8 mA), and input tolerance up to 7V independent of VCC. It serves as a level-shifting combinational logic element in mixed-voltage digital interfaces.

For engineers reviewing the 74VHC08MTR datasheet, 74VHC08MTR pinout, 74VHC08MTR application, or 74VHC08MTR equivalent, key selection criteria include its 2–5.5V operating range, 7V-tolerant inputs, ±8 mA output drive, ESD immunity (2 kV), and SOP-14 package compatibility with legacy 74-series footprints.

Technical Context

The device implements four independent AND gates using sub-micron C2MOS process with buffered outputs, delivering balanced tPLH/tPHL propagation delays and high noise immunity (VNIH/VNIL ≥ 28% VCC). Its input protection circuitry enables safe operation across 0–7V input voltage regardless of VCC.

It supports 5V-to-3V interfacing via rail-to-rail input acceptance and logic-level-compatible output swing, with quiescent ICC ≤ 2 µA at 25°C and dynamic VOLP ≤ 0.8V (max) under 50 pF load-critical for low-noise digital signal integrity in compact PCB layouts.

FAQ

Can 74VHC08MTR operate with V_CC = 3.3 V while accepting 5 V inputs?

Yes. The device supports V_CC from 2 V to 5.5 V and accepts input voltages from −0.5 V to +7.0 V regardless of supply level. At V_CC = 3.3 V, 5 V inputs are safely clamped internally, enabling reliable 5 V-to-3.3 V level translation without external components.

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

The 74VHC08MTR is characterized up to 50 pF load capacitance in AC specs, with t_PD = 5.8 ns (typ) at 5 V. Driving >50 pF increases propagation delay and may raise VOLP; for >100 pF loads, consider adding a buffer stage or reducing trace length to maintain signal integrity.

Does this part support partial power-down operation?

Yes. All inputs feature power-down protection: when V_CC = 0 V, inputs tolerate −0.5 V to +7.0 V without back-current or latch-up. This allows safe connection to live buses during system sleep modes or hot-swap events.

How does its ESD immunity compare to standard 74HC devices?

The 74VHC08MTR provides 2 kV HBM ESD immunity per IEC 61000-4-2 Level 2, exceeding typical 74HC parts (1.5 kV). This is achieved via integrated input protection diodes and optimized C2MOS layout, improving field reliability in handling-prone industrial assembly environments.
