Texas Instruments SN7417NSRG4

Overview

SN7417NSRG4 from Texas Instruments is a hex buffer/driver IC with open-collector high-voltage outputs, designed for TTL-to-MOS level translation and high-current sinking in industrial control and indicator interfacing. It features 15 V maximum output breakdown voltage, 40 mA sink current capability per channel, 14 ns typical propagation delay, and operates across 0°C to 70°C ambient temperature.

For engineers reviewing the SN7417NSRG4 datasheet, SN7417NSRG4 pinout, SN7417NSRG4 application, or SN7417NSRG4 equivalent, this page delivers verified electrical specs, SOP-14 package details, functional role in open-collector driver circuits, and validated alternative options for high-voltage logic interfacing.

Technical Context

The SN7417NSRG4 implements six independent non-inverting open-collector buffers (Y = A) with diode-clamped TTL-compatible inputs and high-voltage tolerant outputs. Its architecture enables direct interface to MOS loads, lamps, relays, and higher-voltage buses without external level-shifting circuitry.

Each output supports up to 15 V off-state voltage and sinks up to 40 mA continuously, with input thresholds of VIH ≥ 2 V and VIL ≤ 0.8 V under 5 V supply. Propagation delay is specified at 6–30 ns depending on load conditions, and power dissipation remains stable at ~145 mW typical.

FAQ

What is the maximum output voltage rating for SN7417NSRG4?

The SN7417NSRG4 has a guaranteed minimum output breakdown voltage of 15 V, meaning it can safely sink current while its output is pulled up to 15 V. This allows direct interfacing with 12 V lamps, relays, and MOS devices without external protection components. Exceeding 15 V risks permanent damage to the output transistor structure in SN7417NSRG4.

Can SN7417NSRG4 replace SN7407NSRG4 in an existing design?

SN7417NSRG4 can replace SN7407NSRG4 only if the application does not require 30 V output tolerance. Both share identical SOP-14 packaging, pinout, 40 mA sink capability, and logic function, but SN7407NSRG4 supports up to 30 V outputs while SN7417NSRG4 is limited to 15 V. Verify that all connected loads remain within 15 V in the target system before substituting SN7417NSRG4.

What is the recommended bypass capacitor for SN7417NSRG4?

Texas Instruments specifies a 0.1 µF ceramic bypass capacitor placed as close as possible to the VCC (Pin 14) and GND (Pin 7) pins of SN7417NSRG4. This minimizes supply noise and prevents transient-induced logic errors during switching. For systems with multiple SN7417NSRG4 devices, use individual 0.1 µF capacitors per IC rather than shared bulk capacitance to ensure effective high-frequency decoupling for SN7417NSRG4.

Does SN7417NSRG4 require pull-up resistors on its outputs?

Yes - all six outputs of SN7417NSRG4 are open-collector and require external pull-up resistors to define the high logic state. The value depends on load current and rise time requirements; typical values range from 1 kΩ (for fast 12 V loads) to 10 kΩ (for 5 V CMOS inputs). Without pull-ups, outputs remain floating and cannot assert a valid HIGH level - a fundamental requirement for correct SN7417NSRG4 operation.

What is the operating temperature range for SN7417NSRG4?

SN7417NSRG4 is rated for commercial-grade operation from 0°C to 70°C ambient temperature. This range covers typical office, consumer, and industrial indoor environments but excludes extended-temperature applications such as automotive under-hood or outdoor telecom enclosures. For operation beyond 70°C, consider military-grade alternatives like SNJ5417J or verify derating curves in the official SN7417NSRG4 datasheet.
