Product details
Overview
74LVC2G53DC from Nexperia is a single-pole double-throw (SPDT) analog multiplexer/demultiplexer in VSSOP8 package, operating from 1.65 V to 5.5 V supply. It features 6.5 Ω typical ON resistance at 3.3 V, 32 mA switch current capability, Schmitt-trigger inputs for noise immunity, and overvoltage-tolerant inputs up to 5.5 V. It enables signal routing in mixed-voltage data acquisition systems.
For engineers reviewing the 74LVC2G53DC datasheet, 74LVC2G53DC pinout, 74LVC2G53DC application, or 74LVC2G53DC equivalent, key selection criteria include ON resistance flatness across voltage range, charge injection (<7.5 pC), -40 °C to +125 °C operation, isolation (-40 dB at 4.5 V), and VSSOP8 footprint compatibility with space-constrained PCB layouts.
Technical Context
The 74LVC2G53DC implements a bidirectional SPDT analog switch controlled by active-low enable (E) and digital select (S) inputs. Its CMOS transmission gate architecture supports rail-to-rail analog signal switching with minimal distortion (0.078% THD at 3.0 V). Schmitt-trigger action on E and S inputs ensures robust timing across full VCC range and ambient temperatures.
Switching performance is defined by propagation delay (≤0.8 ns at 3.0–3.6 V), enable/disable times (≤4.8 ns), and -3 dB bandwidth (300 MHz at 4.5 V). Charge injection (≤7.5 pC) and OFF-state capacitance (6.0 pF) are optimized for precision sampling and low-glitch data paths in ADC/DAC interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65 V to 5.5 V - Enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| ON Resistance (Typ) | 6.5 Ω at VCC = 3.3 V - Minimizes signal attenuation and gain error in precision analog signal paths. |
| Switch Current | ±32 mA - Supports driving moderate loads such as sensor outputs or op-amp inputs without external buffering. |
| Charge Injection | ≤7.5 pC at VCC = 5.5 V - Reduces sampling errors and pedestal distortion in switched-capacitor circuits and sample-and-hold stages. |
| Isolation (OFF-state) | -40 dB at VCC = 4.5 V - Ensures >99% signal rejection between unselected channels in multi-channel data acquisition. |
| Propagation Delay | ≤0.8 ns at VCC = 3.0–3.6 V - Enables high-speed multiplexing in real-time control loops and fast ADC sequencing. |
| Operating Temperature | -40 °C to +125 °C - Qualified for automotive under-hood, industrial motor control, and harsh-environment embedded applications. |
Pinout & Package
VSSOP8 package (SOT765-1): plastic very thin shrink small outline, 8-lead, body width 2.3 mm, lead pitch 0.5 mm, pin 1 index in lower-left corner below marking "V53".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Z | Common I/O terminal | 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; TTL-compatible at 3.3 V. |
| GND | Ground (pins 3 & 4) | Dual ground pins reduce ground bounce and improve PSRR in high-speed switching. |
| S | Select input | Determines channel: S = LOW connects Z↔Y0; S = HIGH connects Z↔Y1; Schmitt-triggered for slow-edge tolerance. |
| Y1 | Independent I/O terminal | Second analog channel; bidirectional and symmetric with Y0 in ON-resistance and capacitance. |
| Y0 | Independent I/O terminal | First analog channel; fully interchangeable with Y1 in routing configuration. |
| VCC | Supply voltage | Power rail for internal logic and switch bias; decoupling capacitor required near pin 8 for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5 V) | Eliminates need for separate voltage translators in mixed-supply systems like MCU + sensor + ADC designs. |
| Low ON-resistance flatness | RON(flat) ≤1.5 Ω at 4.5–5.5 V - Ensures consistent gain and linearity across full analog input swing. |
| Overvoltage-tolerant inputs | Accepts up to 5.5 V regardless of VCC - Allows safe connection to 5 V sensors while powered from 3.3 V. |
| High noise immunity | Schmitt-trigger inputs with hysteresis ≥0.3 V - Prevents false switching from EMI or crosstalk in noisy industrial environments. |
| ESD robustness | HBM >2000 V, CDM >1000 V - Reduces handling sensitivity and improves field reliability in automated assembly lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS5A23157DCUR | Lower ON resistance (0.9 Ω typ at 3.3 V) but narrower VCC range (1.65–5.5 V same); higher charge injection (12 pC). | Preferred for ultra-low-distortion audio routing; less suitable for precision DC-coupled sensor paths due to higher charge injection. | Select TS5A23157DCUR only when ON resistance dominates design priority and charge injection is mitigated externally. |
| ADG723BRMZ-REEL | Higher ON resistance (3.5 Ω typ at 3.3 V), wider temperature range (-40 °C to +150 °C), no Schmitt-trigger inputs. | Better suited for extended-temperature automotive powertrain; lacks slow-edge tolerance for noisy harness environments. | Choose ADG723BRMZ-REEL for under-hood applications requiring >125 °C operation where input edge rate is controlled. |
Compared with TS5A23157DCUR and ADG723BRMZ-REEL, the 74LVC2G53DC delivers optimal balance of low ON resistance (6.5 Ω), ultra-low charge injection (≤7.5 pC), and integrated Schmitt-trigger inputs-making it ideal for cost-sensitive, space-constrained industrial and portable medical signal routing where both precision and noise immunity are critical.

FAQ
What is the maximum allowable switch voltage for the 74LVC2G53DC?
The 74LVC2G53DC supports switch voltages from -0.5 V to VCC + 0.5 V in both enable and disable modes. This allows bidirectional analog signal routing across the full supply rail, provided the voltage remains within this absolute limit to prevent damage or excessive leakage. For example, at VCC = 3.3 V, the switch can safely handle signals from -0.5 V to +3.8 V.
Does the 74LVC2G53DC require external pull-up or pull-down resistors on its control inputs?
No, the 74LVC2G53DC does not require external pull-up or pull-down resistors on E or S inputs because both feature integrated Schmitt-trigger circuitry with defined hysteresis. This ensures clean, noise-immune switching even with slow-rising or slow-falling control signals across the full VCC range (1.65 V to 5.5 V).
Can the 74LVC2G53DC be used to switch differential analog signals?
No, the 74LVC2G53DC is a single-ended SPDT switch and is not designed for differential signal routing. Its architecture provides one common terminal (Z) and two independent terminals (Y0, Y1), all referenced to the same ground. For differential pairs, dedicated differential multiplexers such as the TMUX1574 or ADG774A are required.
How does the 74LVC2G53DC perform in terms of total harmonic distortion (THD)?
The 74LVC2G53DC achieves ≤0.078% THD at VCC = 3.0 V and 4.5 V with RL = 600 Ω and CL = 50 pF. This low distortion level ensures high-fidelity analog signal integrity in audio, sensor, and instrumentation applications where harmonic artifacts must be minimized for accurate measurement or playback.
Is the 74LVC2G53DC pin-compatible with other members of the 74LVC2Gxx series?
No, the 74LVC2G53DC is not pin-compatible with other 74LVC2Gxx devices such as the 74LVC2G66 or 74LVC2G74. Its VSSOP8 pinout (Z, VCC, E, Y0, GND, Y1, GND, S) is functionally unique to the 2-channel analog multiplexer topology and differs from dual-bus-switch or flip-flop configurations in the same package family.
