STMicroelectronics M74HC153B1R

Overview

M74HC153B1R from STMicroelectronics is a high-speed CMOS dual 4-channel multiplexer with pin- and function-compatibility to the 74-series 153. It features symmetrical output impedance (|IOH| = IOL ≥ 4 mA), balanced propagation delays (tPLH ≅ tPHL), and wide supply range (2–6 V). Used in digital logic routing, it selects one of four data inputs per section using address lines A/B and enables/disables outputs via independent strobe inputs (1G/2G).

For engineers reviewing the M74HC153B1R datasheet, M74HC153B1R pinout, M74HC153B1R application, or M74HC153B1R equivalent, key selection criteria include dual independent enable control, guaranteed 16 ns typical propagation delay at 6 V, input noise immunity (VNIH/VNIL ≥ 28% VCC), low quiescent current (ICC ≤ 4 µA), and DIP-16 package compatibility with legacy 74LS153 layouts.

Technical Context

The M74HC153B1R implements two independent 4:1 multiplexers sharing common address inputs (A, B) but with separate strobe (1G, 2G) and output (1Y, 2Y) terminals. Each section routes one of C0–C3 to Y based on binary A/B state when its G is low.

It uses silicon gate C2MOS technology for rail-to-rail input/output swing, ESD-protected inputs, and operates across –55°C to +125°C. Propagation delays are specified separately for data (Cn→Y), address (A/B→Y), and strobe (G→Y) paths, enabling precise timing analysis in synchronous logic designs.

FAQ

Is M74HC153B1R compatible with 5 V TTL logic levels?

Yes. At VCC = 5 V, VIH = 3.15 V (min) and VIL = 1.35 V (max), fully meeting TTL input thresholds. Its VOH = 4.4 V (min) and VOL = 0.26 V (max) at IOL = 4 mA also drive standard TTL loads reliably without level-shifting circuitry.

What is the maximum clock frequency supported for address switching?

Based on worst-case tPHL/tPLH of 30 ns (at VCC = 6 V, TA = 125°C), the device supports address update rates up to ~16 MHz for reliable data capture. For clean setup/hold margins in synchronous systems, ≤10 MHz is recommended with standard 74HC fanout.

Can both sections operate simultaneously with different strobe states?

Yes. 1G and 2G are electrically isolated control inputs. One section can be enabled (G = L) while the other is disabled (G = H), allowing independent data routing or blanking-enabling time-division multiplexing or fault-isolation schemes in real-time systems.

Does M74HC153B1R require external pull-up or pull-down resistors on address or strobe lines?

No. All inputs have defined VIH/VIL thresholds and internal protection diodes. Floating inputs are not permitted per design rules, but no external biasing is needed if driven actively by CMOS or TTL sources meeting the specified voltage and current requirements.
