Diodes Incorporated 74LVC1G08FZ4-7

Overview

74LVC1G08FZ4-7 from Diodes Incorporated is a single 2-input positive AND gate in a 6-pin X2-DFN1410-6 package (1.4 mm × 1.0 mm × 0.4 mm), operating from 1.65 V to 5.5 V, with ±24 mA output drive at 3.3 V, 5.5 V-tolerant inputs, and IOFF partial power-down protection. It enables voltage-level shifting and signal gating in space-constrained portable logic interfaces.

For engineers reviewing the 74LVC1G08FZ4-7 datasheet, 74LVC1G08FZ4-7 pinout, 74LVC1G08FZ4-7 application, or 74LVC1G08FZ4-7 equivalent, key selection criteria include its 0.5 mm pad pitch DFN footprint, sub-6 ns propagation delay at 3.3 V, 5.5 V input tolerance for mixed-voltage interfacing, and IOFF-enabled isolation during system power sequencing.

Technical Context

This device implements standard positive Boolean AND logic (Y = A · B) using CMOS technology with push-pull outputs. Its IOFF circuit actively disables the output when VCC = 0 V, preventing back-current flow into powered-down rails - critical for hot-swap and multi-rail systems.

Input thresholds are voltage-ratio-based (e.g., VIH ≥ 0.7×VCC at 4.5–5.5 V), enabling reliable TTL-level compatibility across supply voltages. The 16 pF typical power dissipation capacitance and low ICC (≤200 μA max) support high-density, low-power logic integration in battery-powered and thermally constrained designs.

FAQ

Can 74LVC1G08FZ4-7 operate reliably at 1.65 V supply?

Yes. The device is fully characterized down to 1.65 V, with guaranteed propagation delay ≤8.0 ns and output drive ≥±4 mA at this minimum voltage. Input thresholds scale with VCC (VIH ≥ 0.65×VCC), ensuring correct logic interpretation even at lowest operating voltage.

Is the NC pin on 74LVC1G08FZ4-7 electrically connected internally?

No. Pin 5 (NC) is an unconnected die pad with no internal bond wire or circuit connection. It must remain floating on the PCB - no solder mask opening, routing, or thermal pad connection is permitted, as it serves only mechanical alignment and package structural integrity.

What is the maximum capacitive load the Y output can drive while maintaining timing specs?

The output maintains specified tPD (≤6.0 ns at 3.3 V) driving up to 30 pF, as defined in the load circuit test condition (RL = 500 Ω, CL = 30 pF). Driving >30 pF increases propagation delay nonlinearly and may degrade edge rate; for >50 pF loads, consider buffer staging or reduced slew-rate variants.

Does IOFF functionality require external biasing or control signals?

No. IOFF activates automatically when VCC drops below ~0.8 V - no external enable/disable pin or configuration is needed. The output enters high-impedance state passively, blocking current flow regardless of input voltage (0–5.5 V), making it ideal for seamless power sequencing in multi-rail systems.
