Nexperia USA Inc. 74LVC10AD,112

Overview

74LVC10AD from Nexperia is a triple 3-input NAND gate logic IC in SO14 (SOT108-1) package, operating from 1.2 V to 3.6 V supply, with 5.5 V-tolerant inputs enabling mixed-voltage level translation between 3.3 V and 5 V systems. It delivers propagation delays as low as 1.5 ns at 3.0–3.6 V and supports industrial temperature range up to +125 °C.

For engineers reviewing the 74LVC10AD datasheet, 74LVC10AD pinout, 74LVC10AD application, or 74LVC10AD equivalent, this device is selected for high-speed, low-power combinational logic in voltage-translating digital interfaces, bus control, and enable gating where input overvoltage tolerance and rail-to-rail compatibility are critical.

Technical Context

The 74LVC10AD implements three independent CMOS-based 3-input NAND gates with identical electrical behavior across all channels. Its input structure accepts voltages up to 5.5 V regardless of VCC (1.2–3.6 V), enabling direct interfacing with legacy 5 V TTL outputs without external level shifters.

Propagation delay is specified down to 1.5 ns per gate at VCC = 3.0–3.6 V and Tamb = –40 °C to +125 °C, while static drive capability includes VOH ≥ 2.2 V at IO = –24 mA (VCC = 3.0 V) and VOL ≤ 0.55 V at IO = 24 mA - confirming robust signal integrity under load.

FAQ

Can 74LVC10AD operate reliably with a 1.2 V supply?

Yes - the 74LVC10AD is fully specified down to 1.2 V supply voltage, with guaranteed functionality including VIH/VIL thresholds, propagation delay (13 ns max at 1.2 V), and output drive strength. This enables use in ultra-low-power battery-operated devices where higher supply rails are unavailable.

Is the GND pin electrically connected to the exposed pad in the SO14 package?

No - the SO14 (SOT108-1) package has no exposed thermal pad. The GND pin (Pin 7) is the sole ground connection; it must be routed to a low-impedance ground plane. Unlike QFN variants, SO14 relies on lead-frame conduction for thermal transfer.

What is the maximum output current per Y-pin when driving capacitive loads?

The 74LVC10AD can sink or source up to ±24 mA per output (1Y/2Y/3Y) while maintaining VOL ≤ 0.55 V and VOH ≥ 2.2 V at VCC = 3.0 V. For capacitive loads exceeding 50 pF, propagation delay increases slightly but remains within datasheet limits up to CL = 50 pF at 3.0–3.6 V.

Does 74LVC10AD require external pull-up or pull-down resistors on unused inputs?

Yes - unused inputs must be terminated to VCC or GND to prevent floating states that cause increased ICC, noise susceptibility, or unintended logic transitions. The device does not include internal weak pull-ups; typical practice is to tie unused A/B/C inputs directly to VCC or GND via short traces.
