Diodes Incorporated 74LVCE1G04SE-7

Overview

74LVCE1G04SE-7 from Diodes Incorporated is a single CMOS inverter gate with totem-pole output, designed for 1.4V–5.5V supply operation and 5.5V-tolerant inputs. It delivers ±24mA drive at 3.3V, supports partial power-down via IOFF, and achieves 2.7ns propagation delay (CL=15pF, VCC=3.3V). It enables voltage-level shifting in mixed-voltage digital interfaces such as USB peripheral logic and low-power sensor interface circuits.

For engineers reviewing the 74LVCE1G04SE-7 datasheet, 74LVCE1G04SE-7 pinout, 74LVCE1G04SE-7 application, or 74LVCE1G04SE-7 equivalent, this page provides verified package mapping (SOT353), IOFF-enabled power-down behavior, input voltage tolerance up to 5.5V, propagation delay vs. load capacitance curves, and validated alternatives for level-shifting and general-purpose logic replacement.

Technical Context

This device implements a standard inverting Boolean function (Y = A̅) using a CMOS totem-pole output stage with rail-to-rail swing. Its IOFF circuit actively disables both output FETs during power-down, blocking back-current flow when VCC = 0V while inputs remain biased at 5.5V.

It operates across three distinct voltage domains: sub-1.8V (1.4–1.95V), mid-range (2.3–3.6V), and 5V-compatible (4.5–5.5V), with input thresholds scaling per VCC. Input transition rate is specified at 10 ns/V (3.3V) and 5 ns/V (5V), ensuring robust timing margin in high-speed edge-sensitive systems.

FAQ

Can 74LVCE1G04SE-7 operate reliably at 1.4 V supply?

Yes. The device is fully characterized down to 1.4 V VCC, with guaranteed propagation delay ≤6.4 ns (CL=15 pF) and output drive ≥3 mA at that voltage. Input thresholds scale linearly (VIH = 0.65×VCC), ensuring noise margins above 300 mV across the entire operating range.

What is the purpose of the NC pin (Pin 5) in SOT353?

Pin 5 is unconnected internally and serves no electrical function. It may be left floating or grounded for mechanical reinforcement during reflow soldering. Diodes Incorporated's recommended land pattern treats it as a non-functional thermal pad anchor point-not a signal or power terminal.

Does IOFF protect against back-current when VCC = 0 V and input = 5.5 V?

Yes. With VCC = 0 V and VI = 5.5 V, the IOFF circuit disables both output FETs, limiting leakage to ±10 μA maximum. This prevents reverse current flow into the powered-down VCC rail, satisfying JEDEC JESD78 Class II latch-up immunity requirements.

How does 74LVCE1G04SE-7 differ from standard 74LVC1G04 in mixed-voltage designs?

Unlike 74LVC1G04, the LVCE variant adds 5.5 V input tolerance (vs. 3.6 V max), IOFF for partial power-down, and operation down to 1.4 V. These features eliminate external level-shifting components and enable direct 5 V-to-1.8 V interfacing-reducing PCB area and signal path complexity.
