Product details
Overview
SN74AUP1G99 from Texas Instruments is a low-power ultra-configurable multiple-function logic gate with 3-state output, operating across 0.8 V to 3.6 V supply range. It supports 16 programmable logic functions-including AND, OR, NAND, NOR, XOR, XNOR, MUX, inverter, and buffer-via four configuration inputs (A–D), features Schmitt-trigger inputs for noise immunity, and delivers tpd ≤ 7.4 ns at 3.3 V in point-to-point signal routing applications.
For engineers reviewing the SN74AUP1G99 datasheet, SN74AUP1G99 pinout, SN74AUP1G99 application, or SN74AUP1G99 equivalent, this device is critical for battery-powered portable systems requiring dynamic logic reconfiguration, Ioff-enabled partial power-down, and ultra-low static current (ICC ≤ 0.9 µA) without sacrificing switching speed or signal integrity.
Technical Context
The SN74AUP1G99 implements a configurable combinational logic core controlled by four binary inputs (A–D) that select one of 16 truth tables, while OE enables/disables the 3-state output. Its Schmitt-trigger inputs provide hysteresis (ΔVT up to 1.31 V at 3 V), enabling robust operation with slow-rising signals and high noise margin.
It integrates Ioff circuitry to isolate outputs during power-down, supports 3.6-V I/O tolerance for mixed-voltage interfacing, and maintains sub-5 pF input capacitance (CI = 1.5 pF) and 5 pF typical power-dissipation capacitance (Cpd) at 3.3 V - key for minimizing dynamic loading in high-density PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface with 1.2-V, 1.8-V, 2.5-V, and 3.3-V logic domains without level shifters. |
| tpd Max | 7.4 ns at 3.3 V, CL = 5 pF - ensures timing-critical path compatibility in portable MCU peripheral control and sensor interface circuits. |
| ICC Max | 0.9 µA at VCC = 3.6 V - extends battery life in always-on wearable and IoT edge nodes where quiescent power dominates energy budget. |
| CI | 1.5 pF - minimizes capacitive loading on driving gates and preserves signal rise/fall times in high-speed interconnects. |
| Ioff | ≤ 0.6 µA at VCC = 0 V - prevents back-current flow during hot-swap or staged power sequencing in multi-rail systems. |
| Hysteresis ΔVT | Up to 1.31 V at VCC = 3 V - rejects EMI-induced glitches on noisy PCB traces or long flex-cable runs. |
| IOZ | ≤ 0.5 µA in 3-state - guarantees negligible leakage when output is disabled, critical for bus arbitration and shared-line contention control. |
Pinout & Package
VSSOP-8 (DCU) package: 2.3 mm × 2.0 mm, 0.5-mm pitch, 8-pin surface-mount with exposed thermal pad (not electrically connected). Pin 1 marked via laser etch; pin 1 quadrant Q3 per tape reel orientation standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable | Active-low control: drives Y to high-impedance when high; ties to VCC via pullup for power-up safety. |
| 2 (A) | Configuration Input | MSB of 4-bit function select code; accepts Schmitt-triggered logic levels for noise-immune programming. |
| 3 (B) | Configuration Input | Second bit of function select code; internally terminated to GND/VCC when unused per TI SCBA004 guidelines. |
| 4 (GND) | Ground Reference | Primary return path for all logic and I/O currents; must be low-inductance connection to minimize ground bounce. |
| 5 (Y) | Configurable Output | 3-state CMOS output supporting 20 mA drive strength; compatible with 3.6-V tolerant I/O standards. |
| 6 (C) | Configuration Input | Third bit of function select code; determines logic family behavior (e.g., inverting vs non-inverting MUX). |
| 7 (D) | Configuration Input | LSB of function select code; selects between complementary logic pairs (e.g., AND/NOR, NAND/OR). |
| 8 (VCC) | Supply Voltage | Core logic and I/O supply; bypass capacitor (0.1 µF ceramic) required within 3 mm of pin for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 0.9 µA across full VCC range - eliminates need for power gating in always-on subsystems. |
| 16-function configurability | Single device replaces multiple discrete logic ICs (e.g., SN74AUP1G00 + SN74AUP1G02 + SN74AUP1G86), reducing BOM count and layout area. |
| Schmitt-trigger inputs | ΔVT ≥ 0.53 V at 1.1 V - enables reliable operation with RC-filtered or slew-limited signals from sensors or mechanical switches. |
| Ioff partial-power-down | Outputs disabled and isolated at VCC = 0 V - allows safe insertion/removal in live backplanes and modular industrial controllers. |
| 3.6-V I/O tolerance | VI/VO rated to 4.6 V absolute max - supports interoperability with legacy 5-V peripherals via resistive level translation or direct connection. |
Applications
| Wearable Sensor Hub | Industrial PLC I/O Module |

IC Role / Device Role / Timing Role: Used as level-translating buffer with VCC = 3.3 V and VI = 12 V (within 3.6-V tolerant spec via internal clamping). Use Value: Avoids discrete MOSFET translators; Ioff protection prevents backfeed into MCU during sleep mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar configurable logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G99DCUR | Higher ICC (10 µA typ), no Schmitt inputs, 1.65–5.5 V VCC range, no Ioff support | Not suitable for battery-critical or partial-power-down designs; requires external hysteresis for noisy inputs | Select only if higher speed (tpd = 3.8 ns @ 3.3 V) and wider voltage range outweigh power/noise trade-offs |
| SN74AUC1G99DBVR | Same AUP-family architecture but SOT-23-6 package (6-pin), missing two configuration inputs (C/D), supports only 4 functions | Limited configurability restricts use to fixed-function roles like buffer/inverter/MUX; no dual-input logic variants | Choose when board space is constrained and full 16-function flexibility is unnecessary |
Compared with SN74LVC1G99DCUR and SN74AUC1G99DBVR, the SN74AUP1G99DCURG4 uniquely balances ultra-low ICC, Schmitt-trigger noise immunity, Ioff isolation, and full 16-function configurability - making it the only option for compact, battery-sensitive, mixed-voltage systems requiring field-programmable logic behavior.

FAQ
What logic functions can the SN74AUP1G99DCURG4 implement?
The SN74AUP1G99DCURG4 supports 16 distinct logic configurations selected via its A–D inputs, including 3-state buffer, inverter, 2-to-1 MUX (standard and inverted), 2-input AND/NAND/OR/NOR/XOR/XNOR (with optional input inversion), and complementary function pairs. All functions operate with Schmitt-trigger inputs and 3-state output control via OE.
How does the SN74AUP1G99DCURG4 handle floating inputs?
The SN74AUP1G99DCURG4 includes an input-disable feature: when OE is high, all inputs (A–D) and the output Y enter a high-impedance state, allowing safe floating of unused inputs without causing undefined logic states or excessive current draw - a key advantage over standard logic gates requiring explicit pullup/pulldown resistors.
What is the recommended power-up sequence for the SN74AUP1G99DCURG4?
To ensure the SN74AUP1G99DCURG4 enters a known high-impedance state at power-up, OE must be held high until VCC stabilizes. TI recommends tying OE to VCC through a pullup resistor (value determined by driver sink capability); the minimum resistance is specified in the datasheet based on the controlling driver's IOL rating.
Does the SN74AUP1G99DCURG4 support mixed-voltage operation?
Yes - the SN74AUP1G99DCURG4 features 3.6-V tolerant I/O, meaning its inputs and output can safely interface with signals up to 3.6 V even when VCC is as low as 0.8 V. This enables seamless integration between 1.8-V or 2.5-V logic domains and 3.3-V peripherals without external level-shifting circuitry.
What packaging and environmental compliance does the SN74AUP1G99DCURG4 have?
The SN74AUP1G99DCURG4 is supplied in a RoHS-compliant, lead-free VSSOP-8 (DCU) package with NiPdAu (NIPDAU) terminal finish, MSL Level-1 rating (unlimited floor life at <30°C/60% RH), and operating temperature range of –40°C to +85°C - meeting industrial and automotive interior requirements.
