Product details
Overview
SN74AS1034ANE4 from Texas Instruments is a hex noninverting buffer/driver IC designed for high-current digital signal distribution in industrial control and legacy TTL-compatible systems. It delivers ±48 mA output drive, operates at 5 V supply, supports 0°C to 70°C ambient, and implements Y = A logic per channel with 6 independent buffers.
For engineers reviewing the SN74AS1034ANE4 datasheet, SN74AS1034ANE4 pinout, SN74AS1034ANE4 application, or SN74AS1034ANE4 equivalent, this page provides verified functional identity, confirmed DIP-14 package mapping, validated 6 ns propagation delay (tPLH/tPHL), exact IOL/IOH drive specs, and two rigorously cross-checked alternative parts for legacy system redesign or obsolescence mitigation.
Technical Context
The SN74AS1034ANE4 uses advanced Schottky-clamped bipolar (AS) technology to achieve high-speed switching with robust capacitive-load drive capability. Its totem-pole output stage enables direct interfacing with multiple TTL or CMOS inputs without external pull-ups.
Each of its six channels operates independently with identical electrical behavior: input threshold VIH = 2 V, VIL = 0.8 V, VOH ≥ 2 V at −48 mA, VOL ≤ 0.5 V at 48 mA, and guaranteed 6 ns max propagation delay under 50 pF load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Output Drive (IOL / IOH) | 48 mA sink / −48 mA source; drives up to 20 standard TTL loads or heavy capacitive traces |
| Propagation Delay | 6 ns max (tPLH/tPHL); supports reliable operation up to ~40 MHz clock distribution |
| Supply Voltage Range | 4.5 V to 5.5 V; compatible with regulated 5 V rails in industrial and telecom backplanes |
| Operating Temperature | 0°C to 70°C; qualified for commercial-grade embedded systems and test equipment |
| Input Thresholds | VIH = 2 V, VIL = 0.8 V; ensures noise margin >0.4 V against TTL-level signals |
| Package Type | PDIP-14 (N package); through-hole mounting for prototyping, repair, and legacy board replacement |
Pinout & Package
SN74AS1034ANE4 is supplied in a 14-pin plastic dual in-line package (PDIP-N), 300-mil width, 0.100" lead pitch, with standard DIP footprint and through-hole soldering compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 1Y, 2Y, 3Y, 4Y, 5Y, 6Y | Independent Output | High-drive buffered outputs; capable of sourcing/sinking 48 mA per channel |
| 7 | GND | Ground reference for all logic and power paths; must be low-impedance connection |
| 14 | VCC | +5 V supply rail; requires local 0.1 µF ceramic decoupling adjacent to pin |
Key Features
| Feature | Design Value |

Use Value: Eliminates signal degradation across 10+ inch traces carrying 20–30 MHz control signals without requiring layout changes. |
Use Scenario: Replacing failed 74AS240 or 74AS244 drivers in discontinued test equipment where space and pinout are fixed. IC Role / Device Role / Timing Role: Drop-in compatible buffer providing identical logic function and drive strength in existing PDIP-14 sockets. Use Value: Restores full functionality without redesign; leverages same 5 V supply and TTL-level signaling as original design. |
| High-Current LED Driver Interface | Signal Level Translation |
Use Scenario: Driving 8-segment LED displays or discrete indicator LEDs directly from microcontroller GPIOs. IC Role / Device Role / Timing Role: Current-boosting buffer converting weak MCU outputs into 40+ mA capable drive signals.

IC Role / Device Role / Timing Role: Logic-level shifter using AS-series input tolerance and 5 V output compliance. Use Value: Provides safe, fast, and deterministic voltage translation without bidirectional complexity or timing skew. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex noninverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AS240N | Octal inverting buffer (8 channels, inverted logic); higher IOL (64 mA) but incompatible logic polarity | Requires PCB trace rewiring or firmware logic inversion to maintain signal integrity | Select only if system design allows inversion and extra channel count is beneficial |
| SN74ALS1034N | Lower drive (24 mA IOL), slower speed (8 ns max delay), ALS-family lower power consumption | Suitable for low-noise, low-power legacy systems where 48 mA drive is unnecessary | Prefer when thermal budget is constrained and full AS-series drive is not required |
Compared with SN74AS1034ANE4, SN74AS240N offers more channels but mandates logic inversion, while SN74ALS1034N reduces drive and speed to cut power-making SN74AS1034ANE4 optimal for high-fanout, timing-critical 5 V TTL interfaces where polarity and performance are fixed requirements.

FAQ
What is the maximum operating frequency supported by SN74AS1034ANE4?
The SN74AS1034ANE4 is characterized for reliable operation up to 40 MHz, based on its 6 ns maximum propagation delay under 50 pF load conditions. While usable in higher-frequency edge-triggered circuits, TI explicitly advises against use above 40 MHz due to timing margin erosion and potential signal integrity issues in real-world layouts.
Is SN74AS1034ANE4 pin-compatible with SN74ALS1034N?
Yes, SN74AS1034ANE4 is pin-compatible with SN74ALS1034N - both use identical PDIP-14 packaging and share the same pinout (1A–6A, 1Y–6Y, GND, VCC). However, SN74AS1034ANE4 delivers double the output current (48 mA vs. 24 mA) and faster propagation (6 ns vs. 8 ns), enabling direct drop-in replacement where enhanced drive or speed is needed.
Does SN74AS1034ANE4 support 3.3 V logic inputs?
No, SN74AS1034ANE4 does not guarantee reliable operation with 3.3 V logic inputs. Its VIH minimum is 2.0 V, but it is designed for 5 V TTL/AS-level signaling. Applying 3.3 V inputs may result in marginal or undefined switching behavior, especially across temperature and process variation - level-shifting circuitry is recommended for mixed-voltage systems.
What decoupling capacitance is recommended for SN74AS1034ANE4?
A minimum of 0.1 µF ceramic capacitor placed within 5 mm of the VCC (pin 14) and GND (pin 7) pins is required for stable operation of SN74AS1034ANE4. For systems with high simultaneous switching noise, adding a 4.7 µF tantalum or aluminum electrolytic capacitor nearby further suppresses low-frequency supply droop during peak 48 mA output transitions.
Can SN74AS1034ANE4 drive multiple 74LS-series inputs directly?
Yes, SN74AS1034ANE4 can drive up to 20 standard 74LS inputs per output channel. With its 48 mA sink capability and 74LS input current of −0.4 mA per gate, the SN74AS1034ANE4 provides ample margin for fan-out expansion in legacy TTL systems without intermediate buffering.
