Diodes Incorporated 74LVC1G11FW4-7

Overview

74LVC1G11FW4-7 from Diodes Incorporated is a single 3-input positive AND gate in a 6-pin X2-DFN1010-6 package, operating from 1.65V to 5.5V supply, with 5.5V-tolerant inputs and ±24mA output drive at 3.3V. It implements the Boolean function Y = A · B · C and supports partial power-down via IOFF circuitry for backflow prevention in mixed-voltage systems such as notebook I/O expansion and USB peripheral logic.

For engineers reviewing the 74LVC1G11FW4-7 datasheet, 74LVC1G11FW4-7 pinout, 74LVC1G11FW4-7 application, or 74LVC1G11FW4-7 equivalent, key selection criteria include input voltage tolerance, IOFF-enabled isolation during power sequencing, propagation delay under 4.1ns at 3.3V/15pF, and compatibility with 1.8V/2.5V/3.3V/5V logic domains in space-constrained portable designs.

Technical Context

This device implements standard CMOS positive-logic AND functionality with three independent inputs (A, B, C) feeding a single push-pull output (Y), enabling synchronous enable gating in control paths. Its IOFF feature actively disables the output when VCC = 0V, preventing current flow between powered and unpowered rails - critical for hot-swap and multi-rail power sequencing.

The logic threshold adapts to supply voltage (VIH = 0.65×VCC min at 1.65–1.95V; 0.7×VCC at 4.5–5.5V), ensuring reliable switching across its full 1.65–5.5V operating range. Propagation delay remains ≤4.1ns (max) at 3.3V with 15pF load, supporting >100MHz toggle rates in low-skew signal conditioning paths.

FAQ

What is the maximum propagation delay of the 74LVC1G11FW4-7 at 5V supply?

The maximum propagation delay is 3.1 ns at VCC = 5.0V ± 0.5V, CL = 15pF, and TA = –40°C to +85°C. This value is measured from any input transition to output response under standard load conditions defined in Figure 1 of the datasheet, confirming suitability for sub-5ns timing-critical paths.

Can the 74LVC1G11FW4-7 safely interface a 5V microcontroller GPIO with a 1.8V FPGA input?

Yes - its inputs tolerate up to 5.5V regardless of VCC level, allowing direct connection of 5V signals to the A/B/C pins while VCC is set to 1.8V. The output Y will swing between 0V and 1.8V, matching the FPGA's input thresholds, eliminating need for external level-shifting components.

Does the IOFF feature require external biasing or configuration?

No - IOFF is fully automatic and requires no external components or control signals. When VCC drops to 0V, internal circuitry disables the output stage within nanoseconds, presenting high-impedance to both VCC and GND rails. This behavior is intrinsic to the silicon design and operates across the full –40°C to +125°C temperature range.

Is the X2-DFN1010-6 package compatible with standard reflow profiles?

Yes - the X2-DFN1010-6 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL1) and supports standard lead-free reflow profiles (peak 260°C, 60 seconds max). Its exposed thermal pad improves solder joint reliability and thermal transfer when soldered using recommended stencil aperture (0.35mm × 0.35mm) and paste volume per IPC-7527.
