Nexperia USA Inc. 74HCT153D,653

Overview

74HCT153D,653 from Nexperia is a dual 4-input multiplexer IC with TTL-compatible input thresholds, independent active-low enable inputs (1E, 2E), common binary select lines (S0, S1), and non-inverting outputs (1Y, 2Y). It operates from 4.5 V to 5.5 V, supports -40 °C to +125 °C ambient range, and delivers propagation delays as low as 11 ns (t_pd, V_CC = 5.0 V, C_L = 15 pF) for high-speed digital routing in address/data selection circuits.

For engineers reviewing the 74HCT153D,653 datasheet, 74HCT153D,653 pinout, 74HCT153D,653 application, or 74HCT153D,653 equivalent, this device serves as a logic-level-selectable signal router in microcontroller peripheral expansion, FPGA I/O consolidation, and industrial control bus arbitration where precise timing, noise immunity, and cascading capability are required.

Technical Context

The 74HCT153D,653 implements two independent 4:1 multiplexers sharing S0/S1 select lines but featuring separate enable inputs (1E, 2E), enabling selective activation of each channel without affecting the other. Its TTL-level input thresholds (V_IL ≤ 0.8 V, V_VIH ≥ 2.0 V at V_CC = 4.5–5.5 V) ensure direct compatibility with legacy 5 V logic families.

Each multiplexer routes one of four data inputs (e.g., 1I0–1I3) to its output (1Y) based on the 2-bit binary code on S0/S1; an asserted (LOW) enable forces the corresponding output LOW regardless of select state. The device uses standard CMOS output stages with VOH ≥ 3.7 V and VOL ≤ 0.4 V at I_O = ±4 mA, supporting robust fan-out and noise margin.

FAQ

Can 74HCT153D,653 operate at 3.3 V?

No. The 74HCT153D,653 is specified only for 4.5 V to 5.5 V supply operation. At 3.3 V, input thresholds (VIH ≥ 2.0 V) remain valid, but VOH drops below 2.4 V and VOL rises above 0.55 V per datasheet Table 6, violating TTL output compatibility and risking downstream logic misreads. Use 74LVC153 for 3.3 V systems.

What is the maximum clock frequency supported for S0/S1 switching?

The device does not have a clock input; S0/S1 are asynchronous control lines. Maximum toggle rate is governed by propagation delay and transition time: with t_pd = 11 ns and t_t = 19 ns (max), minimum pulse width is ~30 ns, supporting up to ~33 MHz data selection rates. For guaranteed timing, limit S0/S1 transitions to ≤25 MHz in production designs.

Is thermal pad connection required for SO16 package?

No. The SO16 (SOT109-1) package used in 74HCT153D,653 has no exposed thermal pad. Thermal management relies on copper pour under pins 8 (GND) and 16 (V_CC) and standard PCB trace width; P_tot derating begins linearly at 12.4 mW/K above 110 °C ambient per datasheet Section 7.

How does the enable input behave during power-up?

At power-up, V_CC ramps from 0 V to 5 V. Per datasheet Section 8, the device remains in high-impedance state until V_CC exceeds 1.5 V (74HCT min VIH), and outputs default LOW only after V_CC stabilizes and 1E/2E are actively driven LOW. To prevent glitches, tie 1E/2E to V_CC via 10 kΩ pull-up resistors until firmware asserts them.
