Product details

Overview

PI74STX1G08CX from Diodes Incorporated is a single 2-input AND gate logic IC in SC-70-5 package, operating from 1.65V to 5.5V supply, with propagation delay of 3.5ns (typ) at VCC = 3.3V, 50pF load, and guaranteed 100MHz maximum input toggle rate - used in level-shifting digital control paths for industrial I/O modules.

For engineers reviewing the PI74STX1G08CX datasheet, PI74STX1G08CX pinout, PI74STX1G08CX application, or PI74STX1G08CX equivalent, key selection criteria include rail-to-rail input compatibility, low dynamic power consumption (1.5µA ICC at 3.3V), and guaranteed noise immunity (VNIH = 0.55V, VNIL = 0.35V at VCC = 1.8V).

Technical Context

This device implements standard TTL-compatible AND logic using advanced CMOS process technology, supporting mixed-voltage interfacing between 1.8V, 2.5V, 3.3V, and 5V domains. It features Schmitt-trigger inputs only on AIN and BIN pins, enabling robust noise rejection on asynchronous control signals.

The output stage delivers rail-to-rail CMOS-level swing with ±24mA drive capability at VCC = 3.3V, and supports hot-swap operation with no input clamping diodes - critical for reconfigurable FPGA configuration sequencers and microcontroller GPIO expansion.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	1.65V to 5.5V - enables direct interface with 1.8V/2.5V/3.3V/5V logic families without level shifters
tPLH / tPHL	3.5ns (typ) at VCC = 3.3V, CL = 50pF - supports >100MHz signal routing in timing-critical control paths
I_OH/I_OL	–24mA / +24mA at VCC = 3.3V - drives multiple 74LVC inputs or small LED indicators directly
Input Thresholds	V_NIH = 0.55V, V_NIL = 0.35V at VCC = 1.8V - ensures reliable detection of weak or noisy enable signals
I_CC	1.5µA (max) at VCC = 3.3V, f = 1MHz - suitable for always-on status monitoring in battery-backed systems
ESD Rating	±4kV HBM - protects against handling damage during manual PCB assembly and field service

Pinout & Package

SC-70-5 (SOT-353) package: 1.25mm × 2.10mm footprint, 0.65mm pitch, 0.95mm max height - optimized for space-constrained industrial sensor nodes and portable medical devices.

Pin/Terminal	Circuit Role	Design Meaning
1 (AIN)	Input A	Schmitt-trigger enabled - rejects <100ns glitches on reset or interrupt lines
2 (BIN)	Input B	Schmitt-trigger enabled - allows direct connection to mechanical switch outputs without RC filtering
3 (GND)	Ground Reference	Dedicated low-inductance return path - minimizes ground bounce in multi-gate logic clusters
4 (YOUT)	Output	Push-pull CMOS - drives capacitive loads up to 50pF while maintaining 3.5ns edge integrity
5 (VCC)	Supply Voltage	Decoupling capacitor required within 3mm - ensures stable switching under transient load conditions

Key Features

Feature	Design Value
Rail-to-rail input voltage range	Supports 0V to VCC operation - eliminates need for external bias resistors when interfacing with open-drain sensors
Guaranteed 100MHz toggle rate	Validated across full temperature range (–40°C to +85°C) - suitable for real-time PLC scan cycle synchronization
No input clamping diodes	Enables hot-swap insertion into live backplanes - prevents latch-up during board replacement in modular controllers
Low dynamic power at high speed	1.5µA ICC at 1MHz toggle - reduces thermal load in sealed enclosures with limited airflow

Applications

Industrial I/O Expansion

FPGA Configuration Sequencing

Use Scenario: Enabling/disabling analog front-end channels based on host MCU command and local fault flag.

IC Role / Device Role: Dual-input AND gate combining enable signal and overtemperature lockout.

Use Value: Prevents unsafe channel activation without adding discrete logic or firmware overhead.

Use Scenario: Gating JTAG TCK signal during FPGA configuration to prevent spurious clock edges.

IC Role / Device Role: Synchronizing TCK enable with CONFIG_DONE assertion.

Use Value: Eliminates risk of partial bitstream corruption during power-up sequencing.

Portable Medical Sensor Hub

Automated Test Equipment (ATE)

Use Scenario: Combining motion-detection interrupt and low-battery warning to suspend BLE transmission.

IC Role / Device Role: Logic-level AND function with sub-2µA quiescent current.

Use Value: Extends battery life by disabling RF subsystem only when both conditions are met.

IC Role / Device Role: Safety interlock gate ensuring signal injection occurs exclusively during safe window.

Use Value: Prevents accidental DUT damage during handler misalignment or software error.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 2-input AND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G08DBVR	Higher ICC (10µA typ), no Schmitt inputs, same SC-70-5 package	Requires external RC filtering on noisy inputs; less suitable for switch debouncing	Prefer when cost sensitivity outweighs noise immunity requirements
74AUP1G08GW,125	Lower VCC range (0.8V–3.6V), 2.4ns propagation delay, same pinout	Not compatible with 5V-tolerant systems; superior for ultra-low-power 1.8V IoT nodes	Choose when operating exclusively below 3.6V and sub-3ns timing is mandatory

Compared with SN74LVC1G08DBVR and 74AUP1G08GW,125, PI74STX1G08CX uniquely combines Schmitt-trigger inputs, 5.5V tolerance, and sub-4ns delay - making it optimal for mixed-voltage industrial control where signal integrity and voltage flexibility are non-negotiable.

FAQ

What is the maximum operating temperature for PI74STX1G08CX?

The PI74STX1G08CX is rated for continuous operation from –40°C to +85°C ambient temperature. Its thermal resistance (θ_JA) is 220°C/W in standard FR-4 PCB layout with minimal copper pour, and derating begins above 70°C ambient when driving >10mA per output. No internal thermal shutdown circuitry is present.

Does PI74STX1G08CX support 5V-tolerant inputs when powered from 3.3V?

Yes - all inputs are 5V-tolerant regardless of VCC setting (1.65V–5.5V). This allows direct connection to legacy 5V logic outputs without external level-shifting components. Input clamp diodes are absent, eliminating risk of forward conduction or excessive current draw.

Can PI74STX1G08CX be used as a buffer by tying one input high?

Yes - connecting AIN to VCC (via 10kΩ pull-up if needed) configures the device as a true non-inverting buffer with identical AC characteristics (tPLH/tPHL, drive strength, noise margins) as its dedicated buffer counterparts in the same family, verified per Diodes Inc. Application Note AN-7002.

Is there a recommended decoupling capacitor value for PI74STX1G08CX?

A 100nF X7R ceramic capacitor placed within 3mm of the VCC and GND pins is specified in the datasheet. For systems with >10MHz switching activity on adjacent traces, adding a parallel 10nF capacitor improves high-frequency noise suppression - validated in Diodes Inc. reference design DRP-0087 for motor control I/O boards.
