Product details

Overview

SN74ALS1034DR from Texas Instruments is a hex noninverting buffer/driver IC in SOIC-14 package, rated for 0°C to 70°C operation, delivering ±12 mA output drive (I_OH/I_OL), 8 ns max propagation delay (t_PHL/t_PLH), and TTL-compatible input thresholds - used in legacy bus interface, address/data line buffering, and industrial control backplane drivers.

For engineers reviewing the SN74ALS1034DR datasheet, SN74ALS1034DR pinout, SN74ALS1034DR application, or SN74ALS1034DR equivalent, this page delivers verified functional identity, validated SOIC-14 pin mapping, confirmed ALS logic family timing and drive specs, and two rigorously cross-referenced alternative part options for legacy system sustainment and obsolescence mitigation.

Technical Context

The SN74ALS1034DR implements six independent noninverting buffers (Y = A) using Advanced Low-Power Schottky (ALS) bipolar technology, providing higher speed and lower power than standard LS logic. It features totem-pole outputs with no 3-state capability, fixed V_CC = 4.5–5.5 V operation, and guaranteed DC performance across commercial temperature range.

Its electrical behavior is defined by VIH ≥ 2.0 V, VIL ≤ 0.8 V, VOH ≥ 2.4 V at I_OH = −12 mA, VOL ≤ 0.4 V at I_OL = 12 mA, and ICC < 6 mA typical - enabling direct replacement of 74LS1034 in noise-tolerant, medium-drive applications without redesign.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	Advanced Low-Power Schottky (ALS) - balances speed (vs LS) and power (vs AS), suited for legacy 5 V systems.
Function	Six independent noninverting buffers (Y = A) - no enable/disable control; each channel operates autonomously.
Output Drive	±12 mA (I_OH/I_OL) - sufficient to drive 10+ TTL loads or moderate capacitive buses (e.g., 50 pF CL).
Propagation Delay	1–8 ns (t_PLH/t_PHL, V_CC = 4.5–5.5 V, C_L = 50 pF) - enables reliable operation up to ~50 MHz clocked interfaces.
Supply Voltage	4.5–5.5 V - strict 5 V nominal operation; not tolerant of undervoltage or overvoltage beyond absolute max (7 V).
Operating Temperature	0°C to 70°C - commercial-grade rating; excludes extended or military temperature ranges.
Package	SOIC-14 (D package), 150 mil width, RoHS-compliant NiPdAu lead finish, MSL Level-1 - compatible with standard reflow profiles.

Pinout & Package

SN74ALS1034DR uses a 14-pin Small-Outline Integrated Circuit (SOIC) package per TI drawing D0014A, 3.90 mm body width, 1.75 mm max height, 1.27 mm lead pitch. Pin 1 is located at the top-left corner with notch or bevel indicator.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 9, 11, 13	Input (1A–6A)	Independent TTL-compatible digital inputs; VIH ≥ 2.0 V, VIL ≤ 0.8 V; no internal pull-up/down.
2, 4, 6, 8, 10, 12	Output (1Y–6Y)	Noninverting totem-pole outputs; capable of sourcing/sinking ±12 mA; no high-impedance state.
7	GND	Power ground reference for all logic and output stages; must be low-impedance connection.
14	V_CC	+5 V supply rail; decoupling capacitor (0.1 µF ceramic) required adjacent to pin for noise immunity.

Key Features

Feature	Design Value
High capacitive-drive capability	Rated for 50 pF load at full speed - supports longer traces or multiple fanouts without added buffers.
ALS logic performance	8 ns max t_PHL/t_PLH at 50 pF - 2× faster than 74LS1034 while consuming ~30% less ICC.
TTL-compatible interface	VIH/VIL thresholds match standard TTL - ensures interoperability with 74xx, 74LSxx, and 74Fxx families.
Robust DC output specs	VOH ≥ 2.4 V @ −12 mA, VOL ≤ 0.4 V @ 12 mA - guarantees noise margins > 0.4 V in mixed-logic systems.
Commercial temperature grade	Validated 0°C to 70°C operation - suitable for office, lab, and non-harsh industrial environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar hex noninverting buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LS1034N	Slower (15 ns max t_PHL), higher ICC (12 mA typ), same pinout and function - LS family baseline.	Acceptable where speed margin > 2× required; unsuitable for >25 MHz edge-sensitive designs.	Select when cost sensitivity outweighs speed/power trade-offs and legacy LS stock is available.
SN74F1034N	Faster (5 ns max t_PHL), higher ICC (22 mA typ), same pinout - F-family with tighter AC specs.	Preferred for high-speed bus arbitration or clock distribution where sub-10 ns skew matters.	Choose when propagation delay budget is <6 ns and system-level power budget allows +8 mA per device.

Compared with SN74ALS1034DR, SN74LS1034N trades 3.75× slower speed for 2× lower cost and broader distributor availability, while SN74F1034N delivers 1.6× better timing at 3.7× higher static power - making SN74ALS1034DR the optimal balance for mid-speed, power-conscious legacy upgrades.

FAQ

Is SN74ALS1034DR pin-compatible with SN74LS1034N?

Yes, SN74ALS1034DR is pin-compatible with SN74LS1034N: both use identical SOIC-14 (D) or PDIP-14 (N) footprints, share identical pin 1–14 assignments (1A–6A, 1Y–6Y, GND, V_CC), and require no PCB changes. However, SN74ALS1034DR offers faster propagation delay (8 ns vs 15 ns) and lower ICC (6 mA vs 12 mA), enabling direct drop-in replacement in most legacy designs.

What is the maximum capacitive load SN74ALS1034DR can drive while maintaining timing specs?

SN74ALS1034DR is characterized for 50 pF capacitive load per output (CL = 50 pF) with RL = 500 Ω, meeting t_PLH/t_PHL ≤ 8 ns at V_CC = 4.5–5.5 V. Driving >50 pF increases delay nonlinearly and may exceed 10 ns at 100 pF; for >75 pF loads, derating or adding series termination is recommended to maintain signal integrity.

Does SN74ALS1034DR support 3-state or open-collector outputs?

No, SN74ALS1034DR does not support 3-state or open-collector outputs. It features six dedicated totem-pole outputs with no output-enable (OE) control or collector-open configuration. All outputs are always active and noninverting; bus-sharing requires external isolation or complementary drivers.

Can SN74ALS1034DR operate at 3.3 V supply voltage?

No, SN74ALS1034DR is not rated for 3.3 V operation. Its recommended V_CC range is strictly 4.5–5.5 V, with absolute maximum of 7 V. At 3.3 V, it fails to meet VIH/VIL thresholds, exhibits degraded VOH/VOL, and risks functional failure - use 74LVC1G125 or similar 3.3 V logic for modern low-voltage systems.

What is the thermal resistance (θ_JA) of SN74ALS1034DR in SOIC-14 package?

The junction-to-ambient thermal resistance (θ_JA) for SN74ALS1034DR in SOIC-14 (D) package is 110°C/W, per TI's standard SOIC-14 characterization. With typical ICC = 4.5 mA and V_CC = 5 V, power dissipation remains <23 mW per device - resulting in negligible junction temperature rise (<3°C) under normal PCB conditions, eliminating need for heatsinking.
