Product details
Overview
74LVC1G53GD,125 from Nexperia is a single-pole double-throw analog multiplexer/demultiplexer IC with digital enable (E) and select (S) inputs, common terminal (Z), and two independent channels (Y0/Y1). It operates from 1.65 V to 5.5 V, delivers ≤6 Ω typical ON resistance at 5 V, supports 32 mA switch current, and functions across –40 °C to +125 °C - used in signal routing for mixed-voltage sensor interfaces and ADC/DAC channel selection.
For engineers reviewing the 74LVC1G53GD,125 datasheet, 74LVC1G53GD,125 pinout, 74LVC1G53GD,125 application, or 74LVC1G53GD,125 equivalent, key selection criteria include its rail-to-rail analog switching capability, Schmitt-trigger control inputs for noise immunity, low charge injection (<7.5 pC), high OFF-state isolation (–40 dB), and compatibility with both 3.3 V and 5 V logic systems.
Technical Context
The 74LVC1G53GD,125 implements a CMOS transmission-gate-based SPDT analog switch architecture with active-low enable and single-bit select logic. Its dual-channel bidirectional operation supports both multiplexing (Y0/Y1 → Z) and demultiplexing (Z → Y0/Y1) modes under synchronous digital control.
Control inputs feature Schmitt-trigger thresholds (VIH = 0.7VCC, VIL = 0.3VCC) enabling robust operation with slow-rising signals, while the switch path maintains flat ON resistance (RON(flat) ≤1.5 Ω at 5 V) and low THD (0.078% typ. at 3 V), making it suitable for precision analog signal routing in data acquisition and audio paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V digital systems without level shifters. |
| ON Resistance (Typ.) | 6 Ω at VCC = 5 V - ensures minimal voltage drop and signal attenuation for 32 mA analog signals. |
| Switch Current Rating | ±32 mA - supports routing of sensor outputs, DAC currents, or audio line-level signals without distortion. |
| Charge Injection | 7.5 pC max at VCC = 5.5 V - limits output glitch amplitude in sample-and-hold or switched-capacitor circuits. |
| OFF-State Isolation | –40 dB at 10 MHz - suppresses crosstalk between inactive Y0/Y1 channels during multiplexed operation. |
| Propagation Delay | 0.6 ns typ. at 5 V - enables high-speed channel switching in real-time signal processing applications. |
| Operating Temperature | –40 °C to +125 °C - qualified for automotive under-hood, industrial PLC, and outdoor embedded environments. |
Pinout & Package
XSON8 package (SOT996-2): plastic extremely thin small outline, no leads, 8-terminal, body size 1.35 × 1.0 × 0.35 mm, thermal pad optional, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Z | Common I/O | Bidirectional analog path shared between Y0 and Y1; must remain within 0–VCC range during switching. |
| E | Enable Input (Active LOW) | Drives entire switch into high-impedance OFF state when HIGH; accepts up to 5 V regardless of VCC. |
| GND | Ground (Pin 3 & 4) | Dual ground terminals reduce ground bounce and improve PSRR in high-frequency analog routing. |
| S | Select Input | Chooses Y0 (S = LOW) or Y1 (S = HIGH) when E = LOW; Schmitt-trigger input rejects noise on control lines. |
| Y1 | Channel 1 I/O | Independent bidirectional analog port; connects to Z only when S = HIGH and E = LOW. |
| Y0 | Channel 0 I/O | Independent bidirectional analog port; connects to Z only when S = LOW and E = LOW. |
| VCC | Supply Voltage | Power rail for internal logic and switch bias; decoupling capacitor required within 1 cm of pin 8. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65 V to 5.5 V operation allows use in battery-powered IoT nodes (1.8 V) and legacy 5 V industrial controllers without external regulators. |
| Low ON Resistance Flatness | ≤1.5 Ω variation across full analog swing - preserves signal linearity in precision instrumentation front-ends. |
| TTL-Compatible Inputs | Accepts 5 V logic inputs at any VCC ≥1.65 V - eliminates need for discrete level translators in mixed-voltage FPGA/ASIC designs. |
| High Noise Immunity | Schmitt-trigger inputs with 0.4 V hysteresis reject EMI and slow-edge interference in motor-control or power-conversion PCB layouts. |
| ESD Robustness | HBM >2000 V and CDM >1000 V - withstands handling and board assembly without additional protection circuitry. |

FAQ
What is the maximum allowable analog signal voltage range for the 74LVC1G53GD,125?
The 74LVC1G53GD,125 supports analog signals from GND to VCC - i.e., rail-to-rail operation. For example, with VCC = 3.3 V, the switch handles signals from 0 V to 3.3 V; with VCC = 5.0 V, it handles 0 V to 5.0 V. Exceeding this range risks latch-up or damage, as absolute maximum switch voltage is limited to VCC + 0.5 V.
Does the 74LVC1G53GD,125 require external pull-up or pull-down resistors on its control inputs?
No, the 74LVC1G53GD,125 does not require external pull-up or pull-down resistors on S or E inputs because its Schmitt-trigger inputs provide defined logic thresholds and inherent noise immunity. However, for system-level robustness in floating-input scenarios (e.g., during power-up), a 100 kΩ pull-down on E is recommended to ensure default OFF-state behavior.
Can the 74LVC1G53GD,125 be used to switch negative analog signals?
No, the 74LVC1G53GD,125 cannot switch negative voltages below GND. Its switch structure is designed for unidirectional ground-referenced analog signals (0 V to VCC). Attempting to apply negative voltages violates the absolute maximum rating of –0.5 V on any pin and may cause forward-biasing of internal ESD diodes or latch-up.
How does the 74LVC1G53GD,125 handle simultaneous switching of multiple devices on the same bus?
When multiple 74LVC1G53GD,125 devices share a common Z node (e.g., in a star-mux configuration), their ON resistances add in series, increasing total path resistance. To avoid signal degradation, ensure only one device is enabled at a time via synchronized E/S control - the 74LVC1G53GD,125 itself provides no arbitration or contention detection.
Is the 74LVC1G53GD,125 compliant with AEC-Q200 for automotive applications?
The 74LVC1G53GD,125 is qualified per AEC-Q100 Grade 1 (–40 °C to +125 °C), not AEC-Q200. While its temperature rating meets under-hood requirements, AEC-Q200 applies to passive components. For automotive use, the 74LVC1G53GD,125 is approved as an AEC-Q100-compliant active component suitable for body electronics and infotainment subsystems.
