Diodes Incorporated 74LVC1G11DW-7

Overview

74LVC1G11DW-7 from Diodes Incorporated is a single 3-input positive AND gate in SOT363 package, operating from 1.65V to 5.5V supply, with ±24mA output drive at 3.3V, 5.5V-tolerant inputs, and IOFF-enabled partial power-down protection. It performs the Boolean function Y = A · B · C and is used for voltage-level shifting and signal isolation in mixed-voltage logic interfaces.

For engineers reviewing the 74LVC1G11DW-7 datasheet, 74LVC1G11DW-7 pinout, 74LVC1G11DW-7 application, or 74LVC1G11DW-7 equivalent, key selection criteria include input voltage tolerance (5.5V), IOFF leakage (<10 μA at –40°C to +85°C), propagation delay (min 0.7 ns, max 4.1 ns at VCC = 3.3V, CL = 15 pF), and SOT363 thermal resistance (θJA = 371 °C/W).

Technical Context

This device implements standard CMOS logic with a push-pull output stage and supports mixed-voltage operation via 5.5V-tolerant inputs across its full 1.65V–5.5V VCC range. Its IOFF circuit actively disables outputs during power-down, preventing back-current flow between powered and unpowered rails.

The gate delivers rail-to-rail output swing, meets JESD22 ESD ratings (2 kV HBM, 200 V MM), and complies with JESD78 latch-up immunity (>100 mA). Propagation delay varies with supply voltage and load capacitance-e.g., 4.1 ns max at 3.3V/15 pF and 4.9 ns max at 3.3V/30–50 pF over –40°C to +85°C.

FAQ

Can the 74LVC1G11DW-7 operate reliably at 1.65V supply while accepting 5.5V inputs?

Yes. The device is fully specified from 1.65V to 5.5V VCC and guarantees 5.5V-tolerant inputs across that entire range. At 1.65V supply, VIH is 0.65×VCC (1.07V min), and input clamp diodes safely shunt excess voltage to VCC or GND without damage or functional disruption.

What is the maximum capacitive load the 74LVC1G11DW-7 can drive while maintaining specified tpd?

The datasheet specifies timing with CL = 15 pF and CL = 30–50 pF. At 3.3V, tpd remains within spec (max 4.1 ns at 15 pF; max 4.9 ns at 30–50 pF) up to 50 pF. Driving >50 pF increases propagation delay nonlinearly and may cause marginal timing in high-speed designs-external buffering is recommended beyond that limit.

Does the IOFF feature require external pull-up or pull-down resistors on the Y output?

No. IOFF actively disables the output MOSFETs when VCC = 0V, placing Y in high-impedance state regardless of input voltages. No external resistors are needed-this is an internal circuit function verified per JESD78 latch-up and ESD test conditions in the datasheet.

Is the SOT363 package of the 74LVC1G11DW-7 compatible with standard SC-70 reflow profiles?

Yes. The SOT363 (SC-70-6) package is JEDEC-standard and compatible with IPC/JEDEC J-STD-020D reflow profiles. Peak temperature must not exceed 260°C for ≤30 seconds, and thermal resistance (θJA = 371 °C/W) has been validated using 2 oz copper FR-4 with minimum recommended pad layout per Diodes AP02001.
