Product details
Overview
SN74AS1032ADRG4 from Texas Instruments is a quad 2-input positive-OR buffer/driver IC in SOIC-14 package, operating at 4.5–5.5 V supply, delivering ±48 mA output drive, with 6.3 ns typical propagation delay (tPLH/tPHL), used for high-speed logic interfacing and bus driving in industrial control backplanes.
For engineers reviewing the SN74AS1032ADRG4 datasheet, SN74AS1032ADRG4 pinout, SN74AS1032ADRG4 application, or SN74AS1032ADRG4 equivalent, this page delivers verified electrical specs, true pin mapping for D-package, functional substitution guidance, and supply-chain context specific to SN74AS1032ADRG4 - not generic 'AS logic'.
Technical Context
This device implements four independent OR gates (Y = A + B) in positive logic using bipolar Schottky (AS) technology, enabling fast switching with low input loading. Each gate features totem-pole outputs - no 3-state or open-collector functionality - and is rated for operation from 0°C to 70°C.
Designed for high capacitive-load driving (e.g., >50 pF), it supports fan-out of up to 40 AS loads per output. Its absolute max ratings include 7 V supply and input voltage limits, while recommended operation strictly requires 4.5–5.5 V VCC and avoids use above 40 MHz due to timing degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input positive-OR (Y = A + B); no NAND/NOR/XOR or configurable logic |
| Supply Voltage (VCC) | 4.5 V to 5.5 V - operation outside this range risks latch-up or parametric failure |
| Output Drive (IOL/IOH) | ±48 mA - enables direct driving of multiple TTL/AS inputs or moderate PCB traces |
| Propagation Delay (tPLH/tPHL) | 6.3 ns max @ CL = 50 pF - defines maximum usable clock/data rate in synchronous systems |
| Operating Temperature | 0°C to 70°C - commercial-grade rating; not qualified for extended or military temperature ranges |
| Input Thresholds (VIH/VIL) | VIH = 2.0 V min, VIL = 0.8 V max - compatible with standard TTL and AS-family logic levels |
| Power Consumption (ICCL) | 24 mA max @ VCC = 5.5 V, VI = 0 - high static current necessitates thermal-aware board layout |
Pinout & Package
SN74AS1032ADRG4 uses a 14-pin SOIC (D) package, 3.9 mm wide, 1.75 mm max height, RoHS-compliant NIPDAU lead finish, MSL Level-1 (unlimited reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | Input A/B per gate | Four independent gate inputs: Pin 1 (1A), Pin 2 (1B), Pin 4 (2A), Pin 5 (2B), Pin 9 (3A), Pin 10 (3B), Pin 12 (4A), Pin 13 (4B) |
| 3, 6, 8, 11 | Output Y per gate | Corresponding OR outputs: Pin 3 (1Y), Pin 6 (2Y), Pin 8 (3Y), Pin 11 (4Y) |
| 7 | GND | Ground reference for all logic and power paths; must be low-impedance connection |
| 14 | VCC | Positive supply rail; decoupling capacitor required within 10 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| High sink/source current | ±48 mA per output enables direct interface to legacy TTL loads without external buffers |
| Low propagation delay | 6.3 ns max ensures timing closure in 40 MHz–60 MHz data paths with 50 pF load |
| AS-series Schottky clamping | Reduces storage time and prevents saturation, enabling faster switching than LS or ALS families |
| Standard DIP/SOIC pin compatibility | Pinout matches industry-standard 14-pin logic layout - simplifies footprint reuse across SN74AS1032A variants |
| Commercial temperature grade | 0°C to 70°C rating targets cost-sensitive industrial and instrumentation applications, not automotive or aerospace |
Applications
| Industrial Backplane Interface | Legacy System Bus Driver |
|---|---|
|
Use Scenario: Driving parallel address/data lines across 15 cm PCB traces in programmable logic controllers. IC Role / Device Role / Timing Role: Quad OR buffer providing level-shifted, high-current drive to reduce signal rise/fall time degradation. Use Value: 48 mA output sustains <10% overshoot on 50 pF net capacitance, eliminating need for discrete transistor buffers. |
Use Scenario: Interfacing microcontroller GPIOs to vintage 8-bit peripheral chips (e.g., Z80, 6502 I/O expanders). IC Role / Device Role / Timing Role: Logic-level translator and fan-out expander between low-drive MCU pins and TTL-compatible peripherals. Use Value: VIH = 2.0 V and VIL = 0.8 V ensure reliable recognition of 3.3 V MCU outputs without pull-up resistors. |
| Test Equipment Signal Conditioning | Digital Panel Meter Input Stage |
|
Use Scenario: Glitch-free OR-ing of multiple fault signals (e.g., overtemp, overcurrent, watchdog timeout) into a single alarm line. IC Role / Device Role / Timing Role: Wired-OR combiner with deterministic propagation (<6.3 ns) for synchronized fault reporting. Use Value: Matched tPLH/tPHL minimizes skew between fault sources, preventing metastability in downstream latching logic. |
Use Scenario: Buffering segmented LED driver enable signals in panel meters with multiplexed displays. IC Role / Device Role / Timing Role: Current-boosting gate for segment select lines requiring >20 mA per channel. Use Value: 48 mA drive capability directly powers common-anode LED segments without external FETs or drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad OR buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AS32DR | Same AS-family OR gate, identical pinout and 6.3 ns delay, but rated for 0°C to 70°C only - no DRG4 suffix variant available | No RoHS exemption marking; same commercial temp grade and SOIC-14 packaging | Select SN74AS32DR if traceability to TI's original AS32 design lineage is preferred and DRG4-specific compliance is not required |
| SN74F32N | F-family (not AS): higher 10 ns delay, lower 20 mA drive, 4.5–5.5 V supply, PDIP-14 only - no SOIC option | Lower speed and drive limit use to non-critical control logic; incompatible footprint prevents drop-in replacement | Choose SN74F32N only for legacy through-hole designs where SOIC mounting is unavailable and 10 ns delay is acceptable |
Compared with SN74AS1032ADRG4, SN74AS32DR offers identical performance and pinout but lacks the DRG4 RoHS-compliant marking and tube packaging; SN74F32N trades speed and drive for broader availability in through-hole systems, requiring PCB redesign.

FAQ
What logic function does the SN74AS1032ADRG4 implement?
The SN74AS1032ADRG4 implements four independent 2-input positive-OR logic functions (Y = A + B) in positive logic. Each gate has dedicated input (A/B) and output (Y) pins, with no programmable or configurable logic modes. It does not support NAND, NOR, XOR, or 3-state operation - its behavior is fixed and defined by the AS-series OR gate architecture documented in the SDAS072B datasheet.
Is SN74AS1032ADRG4 pin-compatible with SN74AS32DR?
Yes, SN74AS1032ADRG4 is pin-compatible with SN74AS32DR: both use SOIC-14 packaging with identical pin assignments for inputs (1A/1B/2A/2B/3A/3B/4A/4B), outputs (1Y/2Y/3Y/4Y), VCC (Pin 14), and GND (Pin 7). The SN74AS1032ADRG4 datasheet explicitly states it is the "driver version of ′AS32", confirming functional and physical equivalence except for RoHS marking and packaging code.
What is the maximum operating frequency supported by SN74AS1032ADRG4?
The SN74AS1032ADRG4 is not characterized for clocked operation but is specified for use up to 40 MHz in data-path applications. TI's datasheet states: "These high sink- or source-current devices are not recommended for use above 40 MHz." This limit arises from cumulative propagation delay (6.3 ns max) and output transition time under load - exceeding 40 MHz risks setup/hold violations in synchronous systems.
Does SN74AS1032ADRG4 support 3-state or open-collector outputs?
No, SN74AS1032ADRG4 does not support 3-state or open-collector outputs. All four outputs are active-push-pull (totem-pole) with no output-enable (OE) control pin. The datasheet logic diagram, pinout table, and electrical characteristics confirm only VOH/VOL parameters - no VOZ, IOZ, or disable timing specs are provided. It is strictly a buffered OR gate, not a bus transceiver.
What is the significance of the 'DRG4' suffix in SN74AS1032ADRG4?
The 'DRG4' suffix in SN74AS1032ADRG4 indicates a SOIC-14 (D) package, tape-and-reel (R) packaging, green/RoHS-compliant (G) finish, and TI's internal revision level (4). Per TI's packaging addendum, 'DRG4' corresponds to an active production part in SOIC with NIPDAU lead finish, MSL Level-1 rating, and 0°C to 70°C temperature grade - distinguishing it from PDIP (N) or ceramic (J/FK) variants of the same base part number.
