STMicroelectronics 74V1T04STR

Overview

74V1T04STR from STMicroelectronics is a single high-speed CMOS inverter with 4.7 ns typical propagation delay at 5 V, 8 mA output drive capability, and 1 µA maximum quiescent current at 25°C. It operates from 4.5 V to 5.5 V, features power-down input protection (0–7 V input tolerance), and enables 5 V-to-3 V interface translation in logic level shifting applications.

For engineers reviewing the 74V1T04STR datasheet, 74V1T04STR pinout, 74V1T04STR application, or 74V1T04STR equivalent, key selection criteria include symmetrical output impedance (|IOH| = IOL ≥ 8 mA), balanced tPLH/tPHL delays, TTL-compatible input thresholds (VIH ≥ 2 V, VIL ≤ 0.8 V), and SOT23-5L package compatibility for space-constrained PCB layouts.

Technical Context

This device implements a three-stage buffered inverter architecture using sub-micron C2MOS technology, delivering high noise immunity and stable rail-to-rail switching. Its input stage accepts voltages from 0 V to 7 V independent of VCC, enabling robust hot-swap and mixed-voltage domain interfacing.

The output stage provides symmetrical sourcing/sinking capability (≥8 mA) with matched tPLH and tPHL delays (typ. 4.7 ns each), ensuring minimal duty-cycle distortion in clock buffering or signal inversion paths across industrial temperature ranges (−55°C to +125°C).

FAQ

What is the maximum input voltage the 74V1T04STR can tolerate?

The 74V1T04STR accepts DC input voltages from −0.5 V to +7.0 V regardless of VCC state, enabling safe operation during hot-swap events or when interfacing with higher-voltage sensors. This specification is explicitly defined in the Absolute Maximum Ratings table and verified across all temperature ranges.

Does the 74V1T04STR require external pull-up or pull-down resistors?

No external biasing resistors are required. The device features internally optimized input structure with defined VIH (≥2 V) and VIL (≤0.8 V) thresholds, and its CMOS output provides rail-to-rail swing without external components. Pull-ups are unnecessary unless driving open-drain loads not specified in the datasheet.

Can the 74V1T04STR operate reliably at −55°C?

Yes. The device is fully characterized and guaranteed to meet all AC/DC specifications across −55°C to +125°C, including propagation delay (4.7 ns typ.), output drive (≥8 mA), and input threshold stability. This qualification is confirmed in the Recommended Operating Conditions and AC Electrical Characteristics tables.

Is Pin 1 (NC) electrically connected internally?

No. Pin 1 is designated "Not Connected" in the official pin description and has no internal bond wire or silicon connection. It may be left unconnected, tied to GND for mechanical reinforcement, or used as a fiducial marker - but it carries zero electrical function or risk of shorting if misrouted.
