Product details

Overview

SN54ALS153J from Texas Instruments is a dual 1-of-4 data selector/multiplexer IC designed for military-grade digital logic systems, featuring two independent 4-input multiplexing sections with common select lines (A/B), individual strobe inputs (1G/2G), and TTL-compatible 300-mil ceramic DIP (J) packaging. It operates across −55°C to 125°C, delivers 24 mA low-level output drive, supports parallel-to-serial conversion, and enables cascading via strobe control - used in avionics data routing and hardened test instrumentation.

For engineers reviewing the SN54ALS153J datasheet, SN54ALS153J pinout, SN54ALS153J application, or SN54ALS153J equivalent, this page provides verified functional identity, military-temperature electrical specs, J-package terminal mapping, real-world use cases in deterministic signal routing, and validated drop-in alternatives for legacy system sustainment.

Technical Context

The SN54ALS153J implements dual independent 4:1 multiplexers using ALS (Advanced Low-Power Schottky) bipolar technology, with full binary decoding via internal inverters and AND-OR gates. Each section has dedicated strobe (G) input enabling/disabling its output without affecting the other section.

Select inputs A and B are shared between both sections, minimizing external address logic. The device uses standard TTL voltage thresholds (V_IL = 0.8 V max, V_IH = 2.0 V min) and drives loads up to 24 mA at V_OL ≤ 0.4 V under recommended conditions (V_CC = 4.5–5.5 V, T_A = −55°C to 125°C).

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	ALS (Advanced Low-Power Schottky) - balances speed (t_PHL/t_PLH ≤ 29 ns) and power (I_CC ≤ 14 mA) for high-reliability embedded logic.
Operating Temperature	−55°C to 125°C - qualified for military/aerospace platforms requiring extended thermal stability without derating.
Supply Voltage	4.5 V to 5.5 V - compatible with standard 5-V TTL rails; absolute max 7 V prevents latch-up during transient overvoltage.
Output Drive	24 mA sink capability - directly interfaces with TTL loads, LEDs, or bus transceivers without external buffers.
Propagation Delay	Max 29 ns (A/B→Y), 15 ns (data→Y) - ensures timing predictability in synchronous control paths with 50-pF load.
Input Compatibility	TTL-level thresholds (V_IH ≥ 2.0 V, V_IL ≤ 0.8 V) - interoperable with 74LS, 74ALS, and 74AS families without level-shifting.

Pinout & Package

Ceramic Dual In-line Package (CDIP), 300-mil body, 16-pin, hermetically sealed - designated "J" package per TI's ordering nomenclature and MIL-PRF-38535 qualified construction.

Pin/Terminal	Circuit Role	Design Meaning
1	1G (Strobe 1)	Active-low enable for first multiplexer section; when high, 1Y is forced high-impedance (not applicable - SN54ALS153J is non-3-state; output disabled = high-impedance only if G=H, but datasheet confirms open-collector/totem-pole output - actual behavior: Y = high when G=H, per function table).
2	1C0 (Data 0, Section 1)	First input of Section 1; selected when A=0, B=0 and 1G=L.
3	1C1 (Data 1, Section 1)	Second input of Section 1; selected when A=1, B=0 and 1G=L.
4	1C2 (Data 2, Section 1)	Third input of Section 1; selected when A=0, B=1 and 1G=L.
5	1C3 (Data 3, Section 1)	Fourth input of Section 1; selected when A=1, B=1 and 1G=L.
6	1Y (Output, Section 1)	Active-high output of Section 1; reflects selected Cx input when 1G=L and A/B match selection code.
7	GND	Power ground reference - must be low-impedance connection for noise immunity in mixed-signal environments.
8	2C0 (Data 0, Section 2)	First input of Section 2; selected when A=0, B=0 and 2G=L.
9	2Y (Output, Section 2)	Active-high output of Section 2; independent timing and enable control from Section 1.
10	2C1 (Data 1, Section 2)	Second input of Section 2; shares A/B select lines but isolated data path.
11	2C2 (Data 2, Section 2)	Third input of Section 2; enables dual-channel routing from separate source buses.
12	2C3 (Data 3, Section 2)	Fourth input of Section 2; supports redundant or mirrored data stream selection.
13	2G (Strobe 2)	Active-low enable for second multiplexer section - allows independent gating of two data paths.
14	V_CC	+5 V supply rail - requires local 0.1-µF ceramic decoupling adjacent to pin for transient suppression.
15	B (Select Bit 1)	MSB of 2-bit binary select code - common to both sections; reduces PCB trace count in multi-channel designs.
16	A (Select Bit 0)	LSB of 2-bit binary select code - shared select logic simplifies address decoder design in microcontroller peripherals.

Key Features

Feature	Design Value
Dual independent 4:1 multiplexers	Enables simultaneous routing of two separate 4-source data streams using shared A/B address lines - reduces FPGA or MCU GPIO usage by 4 pins vs. discrete muxes.
Individual strobe (G) inputs per section	Allows selective enabling/disabling of each multiplexer without software reconfiguration - critical for time-triggered arbitration in flight control I/O modules.
Military temperature range (−55°C to 125°C)	Qualified per MIL-PRF-38535 - eliminates thermal derating calculations and enables direct replacement in legacy defense electronics without redesign.
ALS logic family performance	Delivers 29 ns max propagation delay with 14 mA typical I_CC - achieves 74AS speed at near-74LS power, optimizing SWaP-C in portable test equipment.
Standard 16-pin CDIP (J) package	Hermetic ceramic construction resists moisture ingress and ionizing radiation - meets MIL-STD-883 requirements for long-term reliability in space-qualified subsystems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual 4:1 multiplexer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SNJ54ALS153J	Identical electrical specs, identical J-package, same military qualification - differs only in TI's internal part numbering convention (SNJ prefix denotes QML-38535 Class V).	No functional difference; used interchangeably in DoD procurement where QML certification documentation is required.	Select SNJ54ALS153J when formal QML-38535 Class V certification evidence (e.g., certificate of conformance, lot traceability) is mandated by program office.
SN54AS153J	Faster propagation delay (12.5 ns max vs. 29 ns), higher drive (48 mA vs. 24 mA), but increased ICC (33 mA max vs. 14 mA) and reduced noise margin (V_IL = 0.8 V only).	Better suited for high-speed digital test fixtures where timing closure is critical, but less tolerant of noisy power rails or marginal input signals.	Choose SN54AS153J only when the design requires sub-15 ns propagation and can accommodate higher power dissipation and tighter input threshold control.

Compared with SN54ALS153J, SNJ54ALS153J offers identical performance with certified QML documentation, while SN54AS153J trades power efficiency and noise immunity for raw speed - making SN54ALS153J optimal for thermally constrained, mission-critical routing where reliability outweighs nanosecond gains.

FAQ

What is the maximum operating temperature range for the SN54ALS153J?

The SN54ALS153J is characterized for continuous operation from −55°C to 125°C, meeting MIL-PRF-38535 requirements for military and aerospace applications. This full-range qualification eliminates thermal derating and supports deployment in uncontrolled environmental enclosures such as aircraft bays and ground vehicle engine compartments where ambient extremes occur.

Does the SN54ALS153J support 3-state outputs?

No, the SN54ALS153J does not feature 3-state outputs. Its outputs are standard totem-pole TTL-compatible drivers - when strobe (G) is high, the corresponding Y output is held high (not high-impedance). True 3-state versions are the ′ALS253 and SN74AS253A, as explicitly noted in the SDAS206A datasheet's feature list.

What package type is used for the SN54ALS153J?

The SN54ALS153J uses a 16-pin Ceramic Dual In-line Package (CDIP) with 300-mil body width, designated "J" per TI's packaging nomenclature. This hermetically sealed ceramic package provides superior moisture resistance, thermal cycling endurance, and radiation tolerance compared to plastic DIP variants.

How many independent multiplexer sections does the SN54ALS153J contain?

The SN54ALS153J contains two fully independent 1-of-4 multiplexer sections (Section 1 and Section 2), each with dedicated data inputs (1C0–1C3, 2C0–2C3), strobe inputs (1G, 2G), and outputs (1Y, 2Y). Select lines A and B are shared between sections to minimize external address logic.

What is the maximum propagation delay for the SN54ALS153J at worst-case conditions?

The maximum propagation delay for the SN54ALS153J is 29 ns (t_PLH) from select inputs A or B to output Y, and 15 ns (t_PLH) from any data input (Cx) to Y, measured under worst-case conditions: V_CC = 4.5 V, C_L = 50 pF, R_L = 500 Ω, and temperature spanning −55°C to 125°C.
