Diodes Incorporated 74LVCE1G08W5-7

Overview

74LVCE1G08W5-7 from Diodes Incorporated is a single 2-input positive AND gate in SOT25 package, operating from 1.4V to 5.5V supply, with 5.5V-tolerant inputs, ±24mA output drive at 3.3V, and IOFF-enabled partial power-down protection. It performs Boolean Y = A • B and is used in voltage level shifting between mixed-voltage domains in portable electronics.

For engineers reviewing the 74LVCE1G08W5-7 datasheet, 74LVCE1G08W5-7 pinout, 74LVCE1G08W5-7 application, or 74LVCE1G08W5-7 equivalent, key selection criteria include supply voltage flexibility (1.4–5.5V), 5.5V input tolerance for level translation, IOFF functionality for hot-swap safety, propagation delay down to 0.6ns at 3.3V/15pF, and SOT25 footprint compatibility with space-constrained PCB layouts.

Technical Context

This device implements standard totem-pole CMOS logic with dual rail-compatible inputs and a single buffered AND output. Its IOFF circuit actively disables the output during VCC = 0V, preventing back-current flow into powered subsystems - critical for partial-power-down systems like USB peripherals or hot-pluggable modules.

The gate supports dynamic operation across five voltage tiers (1.5V, 1.8V, 2.5V, 3.3V, 5V) with characterized tPD as low as 0.6ns (max 2.9ns) at 3.3V/15pF, and input transition rate limits of 5–20 ns/V depending on VCC, ensuring robust timing margin in mixed-signal environments.

FAQ

Can the 74LVCE1G08W5-7 operate reliably at 1.4V supply?

Yes. The device is fully characterized from 1.4V to 5.5V, with guaranteed tPD ≤7.2ns at 1.5V/15pF and VIH/VIL thresholds scaled to 65% and 35% of VCC respectively. At 1.4V, input thresholds are ~0.91V (high) and ~0.49V (low), ensuring noise margins >200mV with typical 1.8V logic drivers.

What happens to the output when VCC = 0V and an input is pulled to 5V?

The IOFF circuit disables the output stage, limiting leakage current to ±10μA maximum. This prevents reverse current from the 5V input source into the unpowered VCC rail or GND, satisfying JEDEC JESD78 Class II latch-up immunity (>100mA) and protecting upstream drivers.

Is the SOT25 package thermally adequate for continuous 24mA output switching?

Yes. With θJA = 204°C/W on standard FR-4 (2oz Cu), dissipating 75mW (24mA × 3.3V × 0.95 duty) raises junction temperature by ~15°C above ambient - well within the –40°C to +150°C TJ rating. Thermal derating is unnecessary below 85°C ambient.

Does the 74LVCE1G08W5-7 require external pull-up or pull-down resistors on unused inputs?

Yes. Per datasheet Note 4, unused inputs must be tied to VCC or GND to prevent floating states that increase ICC and cause unpredictable output behavior. A 10kΩ pull-up to VCC is recommended for unused inputs in systems where default-high logic is acceptable.
