NXP Semiconductors 74HCT4052D,112

Overview

74HCT4052D,112 from Nexperia is a dual 4-channel analog multiplexer/demultiplexer (2 × SP4T) designed for bidirectional signal routing in mixed-signal systems. It features TTL-compatible logic inputs (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), ±5 V analog signal handling, 60 Ω typical ON resistance at VCC = 4.5 V/VEE = −4.5 V, and operates across −40 °C to +125 °C - enabling use in industrial sensor front-ends and test equipment switching matrices.

For engineers reviewing the 74HCT4052D,112 datasheet, 74HCT4052D,112 pinout, 74HCT4052D,112 application, or 74HCT4052D,112 equivalent, key selection criteria include its dual independent 4:1 analog switch architecture, rail-to-rail analog voltage range (−5 V to +5 V), break-before-make timing, and SO16 package compatibility with legacy PCB layouts.

Technical Context

The 74HCT4052D,112 implements two independent single-pole quad-throw analog switches sharing common digital control lines (E, S0, S1). Each switch routes one of four independent terminals (nY0–nY3) to a common terminal (nZ) under 2-bit binary select logic, with active-low enable disabling all channels simultaneously.

Its CMOS-based transmission gate design supports bidirectional analog/digital signal flow, includes input clamp diodes for overvoltage protection, and provides logic-level translation between 5 V TTL control signals and ±5 V analog domains - critical for interfacing microcontrollers to bipolar sensor or DAC/ADC circuits.

FAQ

What is the maximum analog signal voltage range supported by the 74HCT4052D,112?

The 74HCT4052D,112 supports analog signals from VEE to VCC. With VCC = 4.5 V and VEE = −4.5 V, it handles −5 V to +5 V signals - verified per datasheet Table 5 and Figure 6. This range accommodates bipolar sensor outputs, audio signals, and industrial ±V references without external level shifting.

Does the 74HCT4052D,112 support break-before-make switching?

Yes, the 74HCT4052D,112 incorporates built-in break-before-make timing, confirmed in Section 2 ("Features and benefits") of the datasheet. This prevents momentary short-circuits between channels during state transitions - critical for avoiding signal glitches in precision analog routing applications.

Can the 74HCT4052D,112 operate with a single 5 V supply?

Yes, the 74HCT4052D,112 can operate with VCC = 5 V and VEE = GND (0 V), supporting 0 V to 5 V analog signals. However, its full ±5 V capability requires dual supplies (e.g., VCC = 5 V, VEE = −5 V), as specified in Table 5 and Figures 5–6 of the datasheet.

What is the typical ON resistance of the 74HCT4052D,112 at 5 V operation?

At VCC = 4.5 V and VEE = −4.5 V, the 74HCT4052D,112 exhibits 60 Ω typical ON resistance (Table 6, RON(peak)). At VCC = 5.0 V and VEE = 0 V, typical RON is 70 Ω - values confirmed in both "Static characteristics" tables for 74HCT4052 under recommended operating conditions.

Is the 74HCT4052D,112 pin-compatible with other packages in the same family?

No - the 74HCT4052D,112 specifically denotes the SO16 (SOT109-1) package. While functional equivalents exist in TSSOP16 (74HCT4052PW), DHVQFN16 (74HCT4052BQ), and DHXQFN16 (74HCT4052BZ), each has distinct pinouts and footprints. The SO16 variant maintains legacy board compatibility but is not mechanically interchangeable.
