NXP Semiconductors 74HCT4016D,112

Overview

74HCT4016D,112 from NXP Semiconductors is a quad bilateral analog switch IC with four independent transmission gates, each featuring active-HIGH enable control, 120 Ω typical ON-resistance at 4.5 V, <20 ns turn-ON time, and operation across −40 °C to +125 °C. It serves as a signal routing element in analog multiplexing, chopper amplifier, and modulation circuits where bidirectional low-distortion switching is required.

For engineers reviewing the 74HCT4016D,112 datasheet, 74HCT4016D,112 pinout, 74HCT4016D,112 application, or 74HCT4016D,112 equivalent, key selection criteria include guaranteed TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), ≤5 pF switch capacitance, −60 dB crosstalk suppression at 1 MHz, and SO14 package compatibility with industrial signal conditioning and test equipment designs.

Technical Context

The 74HCT4016D,112 implements four electrically symmetric transmission gates using CMOS silicon-gate technology, each with Yn/Zn bidirectional I/O terminals and dedicated En enable inputs. Its TTL-compatible input stage ensures direct interfacing with 5 V microcontrollers and logic families without level shifting.

Each switch exhibits rail-to-rail analog conduction capability (VS range: GND to VCC), built-in break-before-make timing to prevent channel shorting during state transitions, and low charge injection (<1 pC) critical for sample-and-hold stability. The device operates within 4.5–5.5 V supply range and maintains ≤0.8% sine-wave distortion at 1 kHz under 4 V_p-p input.

FAQ

What is the maximum analog signal voltage range supported by the 74HCT4016D,112?

The 74HCT4016D,112 supports analog signals from GND to VCC (4.5–5.5 V). This rail-to-rail conduction range allows full utilization of the supply without clipping, provided both Yn and Zn terminals remain within this window. Exceeding these limits risks latch-up or permanent damage, as confirmed in the Absolute Maximum Ratings table (VS range: −0.5 V to VCC + 0.5 V).

Does the 74HCT4016D,112 require external pull-up resistors on its enable inputs?

No, the 74HCT4016D,112 does not require external pull-up resistors on E0–E3 pins. Its TTL-compatible input structure guarantees recognition of logic HIGH at ≥2.0 V and logic LOW at ≤0.8 V, enabling direct connection to 5 V microcontroller GPIOs or logic gates. Internal input protection diodes and defined threshold voltages eliminate the need for external biasing components.

How does the 74HCT4016D,112 achieve break-before-make behavior?

The 74HCT4016D,112 achieves break-before-make through internal propagation delay asymmetry: tPHZ/tPLZ (turn-OFF) is specified at 23 ns typical, while tPZH/tPZL (turn-ON) is 19 ns typical at VCC = 4.5 V. This intentional 4 ns delay margin ensures the previously enabled channel fully opens before the next closes, preventing momentary shorts-a feature explicitly documented in the General Description section.

Can the 74HCT4016D,112 be used in audio applications up to 20 kHz?

Yes, the 74HCT4016D,112 supports full-audio bandwidth operation: its −3 dB frequency response is 150 MHz at VCC = 4.5 V, and measured sine-wave distortion is only 0.80% at 1 kHz with 4 V_p-p input. At 20 kHz, signal integrity remains intact due to low 5 pF switch capacitance and <120 Ω ON-resistance, making it suitable for line-level audio gating and routing.

What is the thermal derating behavior of the 74HCT4016D,112 in SO14 package?

In its SO14 package, the 74HCT4016D,112 has a power dissipation limit of 500 mW up to +70 °C, with linear derating of 8 mW/K above that temperature. At +125 °C ambient, maximum allowable power drops to 500 mW − (55 K × 8 mW/K) = 60 mW. This reflects the plastic mini-pack thermal specification confirmed in the "RATINGS" section of the datasheet.
