Texas Instruments SN74F153DR

Overview

SN74F153DR from Texas Instruments is a dual 4-line to 1-line data selector/multiplexer IC operating at 5 V, featuring two independent 4:1 multiplexing sections with common select inputs (A, B), separate strobe (1G, 2G) enable controls, and TTL-compatible input/output levels. It supports parallel-to-serial conversion and cascading in digital logic systems such as address decoding, data routing, and ALU control paths.

For engineers reviewing the SN74F153DR datasheet, SN74F153DR pinout, SN74F153DR application, or SN74F153DR equivalent, key selection criteria include its 16-pin SOIC package, 0°C to 70°C industrial temperature range, 7 ns typical propagation delay (tPLH/tPHL), 20 mA output drive capability, and compatibility with standard 74F logic families in combinational control circuits.

Technical Context

The SN74F153DR implements two independent 4:1 multiplexer sections sharing select lines A and B, each with dedicated active-low strobe inputs (1G, 2G) enabling section-level gating and hierarchical signal routing. Its internal architecture uses binary-decoded AND-OR logic with inverters and drivers for full decoding and fanout support.

It operates strictly within 4.5 V to 5.5 V supply range, delivers VOH ≥ 2.5 V at IOH = −1 mA and VOL ≤ 0.5 V at IOL = 20 mA, and meets F-series TTL timing with tPHL/tPLH ≤ 12 ns across temperature extremes (0°C to 70°C).

FAQ

What is the maximum clock frequency supported by SN74F153DR in a multiplexing application?

The SN74F153DR does not operate on a clock signal - it is a combinational logic device. Its usable toggle rate depends on propagation delay and system timing margins. With a maximum tPHL/tPLH of 12 ns, it supports reliable data routing in systems with cycle times ≥24 ns (i.e., ≤41.7 MHz effective rate), assuming proper setup/hold timing for select and strobe inputs. The SN74F153DR itself imposes no internal clocking limitation.

Does SN74F153DR support 3.3 V logic interfacing?

No, the SN74F153DR is a 5 V-only TTL device with VCC specification of 4.5 V to 5.5 V and input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) optimized for 5 V operation. Direct connection to 3.3 V logic may result in marginal or non-functional VIH recognition. Level-shifting circuitry or a CMOS alternative like SN74HC153DR is required for 3.3 V system integration. The SN74F153DR must be powered from a stable 5 V rail.

Are the outputs of SN74F153DR inverted, and how does that affect system design?

Yes, the SN74F153DR outputs (1Y, 2Y) are active-high but logically inverted relative to the selected data input - i.e., Y = (C0·A′·B′ + C1·A·B′ + C2·A′·B + C3·A·B)′. This inversion is inherent to its AND-OR gate structure. System design must account for this polarity: either complement input data sources or add external inversion if true non-inverting multiplexing is required. The SN74F153DR datasheet function table confirms this behavior across all select/strobe combinations.

Can SN74F153DR be used to implement a 1-of-8 decoder?

Not directly - the SN74F153DR is a dual 4:1 multiplexer, not a decoder. However, it can be configured as an 8-input multiplexer by cascading two SN74F153DR devices: use the third select bit to enable one device's strobe while disabling the other, then wire their outputs to an OR gate (or open-collector wired-OR with pull-up). This implementation consumes additional gates and increases propagation delay beyond the SN74F153DR's native 12 ns spec. A dedicated 3-to-8 decoder (e.g., SN74F138) is more efficient for that function.

What is the recommended bypass capacitor value for SN74F153DR on a PCB?

Texas Instruments recommends a minimum 0.1 µF ceramic capacitor placed as close as possible to the VCC (Pin 14) and GND (Pin 7) pins of the SN74F153DR to suppress high-frequency switching noise. For boards with multiple 74F devices or high-current loads, adding a bulk 4.7 µF–10 µF tantalum or aluminum electrolytic capacitor near the power entry point improves low-frequency stability. Proper placement and short traces are essential - the SN74F153DR's fast edge rates make localized decoupling critical for signal integrity.
