SN74AUC1G66DCKRE4

Overview

The SN74AUC1G66DCKRE4 is a single bilateral analog switch from the Texas Instruments AUC series, housed in a DCK (SC-70) package. It operates within a supply voltage range of 0.8 V to 2.7 V and supports both analog and digital signals between VCC and GND. Key electrical parameters include an on-state resistance of typically 9 Ω at 2.3 V and 10 Ω at 1.65 V, with a maximum off-state leakage current of ±0.1 μA at 2.7 V. Propagation delay is typically 0.2 ns at 1.8 V with a 15 pF load. The device features ESD protection exceeding 2000 V (Human-Body Model) and 1000 V (Charged-Device Model), with an operating temperature range of -40 °C to +85 °C.

Feature Summary

Supports sub-1-V operation for low-voltage applications
Provides high linearity and low on-state impedance
Offers robust ESD protection across multiple standards

Applications

Signal gating and chopping circuits
Modulation and demodulation systems
Signal multiplexing for ADC and DAC interfaces

Procurement Notes

Verify the 'E4' suffix indicates lead-free compliance and RoHS status per the manufacturer's Package Option Addendum. Confirm the DCK package designation matches the required SC-70 footprint dimensions. Ensure the ordering part number corresponds to the specific reel quantity and tape-and-reel quadrant assignment specified in the packaging data.

Selection Notes

Select this component when a single-channel bilateral switch is required for signals ranging from 0.8 V to 2.7 V. The SC-70 package is suitable for space-constrained designs. Verify that the application signal levels remain within the VCC-to-GND range to ensure proper transmission in either direction without external level shifting.

Part Context

This device belongs to the SN74AUC1G66 family of single bilateral analog switches. The DCK variant specifically utilizes the SC-70 surface-mount package. The 'E4' suffix denotes environmental compliance, specifically lead-free manufacturing and RoHS adherence, distinguishing it from non-compliant variants within the same functional family.
