Diodes Incorporated 74LVCE1G08FZ4-7

Overview

74LVCE1G08FZ4-7 from Diodes Incorporated is a single 2-input positive AND gate in DFN1410 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 logic for voltage-level shifting and mixed-voltage interface applications in portable electronics.

For engineers reviewing the 74LVCE1G08FZ4-7 datasheet, 74LVCE1G08FZ4-7 pinout, 74LVCE1G08FZ4-7 application, or 74LVCE1G08FZ4-7 equivalent, key selection criteria include supply voltage flexibility (1.4–5.5V), 5.5V input tolerance, IOFF leakage <10μA, propagation delay ≤2.9ns at 3.3V/15pF, and DFN1410 thermal resistance (θJA = 430°C/W).

Technical Context

This device implements standard totem-pole CMOS output logic with true positive AND functionality (Y = A AND B). Its IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0V while inputs remain biased up to 5.5V.

Designed for mixed-voltage system interfacing, it supports direct TTL-level compatibility and operates across five discrete supply rails (1.5V, 1.8V, 2.5V, 3.3V, 5V) with characterized switching speed and input transition rate limits (e.g., 10 ns/V at 3.3V).

FAQ

What is the maximum input voltage the 74LVCE1G08FZ4-7 can tolerate when VCC = 1.4V?

The device accepts input voltages up to 5.5V regardless of VCC level, including at minimum 1.4V supply. This is enabled by internal input protection structures that decouple input clamping from VCC rail-verified per datasheet Absolute Maximum Ratings (VI = –0.5V to 6.5V) and Recommended Operating Conditions (VI = 0 to 5.5V).

Does the DFN1410 package of 74LVCE1G08FZ4-7 support reflow soldering per IPC-J-STD-020?

Yes, the DFN1410 package is rated MSL1 (Moisture Sensitivity Level 1) and qualified for standard Pb-free reflow profiles up to 260°C peak temperature. The 0.5mm pitch and wettable flank design ensure reliable solder joint formation and automated optical inspection (AOI) compatibility per Diodes' AP02001 land pattern recommendations.

How does IOFF functionality behave when VCC is ramped down during system shutdown?

IOFF activates automatically when VCC drops below ~0.8V, disabling the output FETs and limiting leakage to ±10μA maximum. This prevents reverse current flow from powered inputs (e.g., 5V bus) into the de-energized VCC rail-critical for preserving upstream regulator stability and avoiding latch-up in multi-rail systems.

Can 74LVCE1G08FZ4-7 drive a 50pF load at 3.3V while maintaining timing specifications?

Yes, propagation delay remains within specification (tpd ≤3.6ns) at 3.3V with 50pF load, as confirmed in the Switching Characteristics table (CL = 50pF column). However, output rise/fall times increase slightly versus 15pF testing, and total power dissipation rises proportionally to Cpd × V² × f-designers should verify thermal margin using θJA = 430°C/W.
