Product details

Overview

SN7417D 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 (40 mA per channel) in industrial control and indicator driving applications. It features 15 V output breakdown voltage, 14 ns typical propagation delay, and operates from 4.75 V to 5.25 V supply.

For engineers reviewing the SN7417D datasheet, SN7417D pinout, SN7417D application, or SN7417D equivalent, key selection criteria include open-collector sink capability, 15 V output voltage tolerance, SOIC-14 package compatibility, and TTL input compatibility with diode-clamped inputs for transmission-line effect mitigation.

Technical Context

The SN7417D implements six independent non-inverting buffers (Y = A) with open-collector outputs, enabling wired-OR logic and direct interface to higher-voltage loads such as lamps or relays. Each output supports up to 40 mA sink current at V_OL ≤ 0.7 V.

It is characterized for operation from 0 °C to 70 °C, with TTL-compatible input thresholds (V_IL = 0.8 V, V_IH = 2 V), and includes diode-clamped inputs to suppress ringing on long traces-critical for reliable signal integrity in industrial backplanes and display driver circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
Function	Six independent non-inverting open-collector buffers (Y = A)
Output breakdown voltage	15 V - enables direct drive of 12 V indicator lamps or relay coils without external level-shifting circuitry
Max sink current per output	40 mA - sufficient to drive multiple TTL inputs or low-power LEDs in parallel
Propagation delay (t_PLH/t_PHL)	6–30 ns - supports timing-critical bus buffering up to ~30 MHz clock domains
Supply voltage range	4.75 V to 5.25 V - tightly regulated 5 V rail requirement for stable TTL interfacing
Input compatibility	Fully compatible with standard TTL families - eliminates need for input level translators in mixed-logic systems
Operating temperature	0 °C to 70 °C - suitable for commercial-grade embedded controllers and consumer electronics

Pinout & Package

SN7417D is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package measuring 8.65 mm × 3.91 mm, with standard JEDEC MS-012AC footprint and gull-wing leads for surface-mount assembly.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 9, 11, 13	Input A1–A6	TTL-compatible digital inputs; internally diode-clamped to minimize transmission-line reflections
2, 4, 6, 8, 12, 14	Output Y1–Y6	Open-collector outputs; require external pull-up to load voltage (up to 15 V); sink up to 40 mA each
7	GND	Ground reference for all inputs, outputs, and internal circuitry; must be low-impedance connection
14	V_CC	5 V power supply pin; requires local 0.1 µF bypass capacitor per TI layout guidelines
NC (pins 1, 5, 7, 11, 15, 17 on full family die)	No internal connection	Not bonded in SOIC-14 variant; left unconnected on PCB

Key Features

Feature	Design Value
High sink-current capability	40 mA per output - drives lamps, relays, or multiple TTL loads without external transistors
Open-collector high-voltage outputs	15 V breakdown rating - interfaces directly to 12 V logic or analog subsystems
TTL input compatibility	Standard VIH/VIL thresholds (2 V/0.8 V) and diode-clamped inputs - ensures robust noise immunity and signal integrity
Low propagation delay	14 ns typical - supports high-speed data path buffering in microcontroller peripheral interfaces
Wide operating margin	Specified across 4.75–5.25 V supply - accommodates nominal 5 V rail tolerances in industrial power supplies

FAQ

What is the maximum output voltage rating for SN7417D?

The SN7417D has a minimum output breakdown voltage of 15 V, meaning its open-collector outputs can safely sink current when pulled up to 15 V. This rating is confirmed in the Absolute Maximum Ratings table and applies specifically to the SN7417D and SN7417 variants-not the SN7407 series, which supports 30 V.

Is SN7417D pin-compatible with SN7407D?

Yes, SN7417D is pin-compatible with SN7407D in the same SOIC-14 package: both share identical pin assignments for inputs (A1–A6), outputs (Y1–Y6), GND, and V_CC. However, SN7417D is rated for 15 V output voltage while SN7407D supports 30 V-so substitution requires verification of load voltage compliance.

What is the typical propagation delay of SN7417D?

The SN7417D exhibits a typical propagation delay of 14 ns under standard conditions (V_CC = 5 V, T_A = 25 °C, R_L = 110 Ω, C_L = 15 pF), with t_PLH and t_PHL ranging from 6 ns (min) to 30 ns (max). This value is explicitly specified in the Switching Characteristics section of the SDLS032H datasheet.

Does SN7417D require external pull-up resistors on its outputs?

Yes, SN7417D outputs are open-collector and must be externally pulled up to the target load voltage (up to 15 V). The datasheet specifies no internal pull-ups; design examples consistently show external resistors tied to V_LOAD, with values selected based on sink current and voltage drop requirements.

What is the operating temperature range for SN7417D?

The SN7417D is characterized for commercial operation from 0 °C to 70 °C, as stated in the Recommended Operating Conditions table. This range applies specifically to the SN7417D and SN7417 variants; military-grade SN5417 parts extend to –55 °C to 125 °C.
