SN74S1053NE4

Specialty Logic Overview

The SN74S1053NE4 is a 16-bit Schottky barrier diode bus-termination array manufactured by Texas Instruments. It features a PDIP-20 package and operates within a temperature range of 0°C to 70°C. The device includes two VCC pins and two GND pins, with sixteen D terminals for connection. Key electrical characteristics include a static forward voltage of 0.85V to 1.3V depending on current, a peak forward voltage of 1.45V at 200mA, and a reverse recovery time of 8ns to 16ns. Total capacitance ranges from 4pF to 16pF based on reverse voltage.

Specialty Logic Feature Summary

• Designed to reduce reflection noise on memory bus lines
• Consists of a 16-bit high-speed Schottky diode array suitable for clamping to VCC and/or GND
• Repetitive peak forward current capability up to 200 mA

Specialty Logic Applications

• Suppressing negative transients caused by transmission-line reflections
• Mitigating crosstalk in bus-oriented systems
• Reducing switching noise on clocked device inputs

Specialty Logic Procurement Notes

Verify the specific ordering suffix 'E4' indicates lead-free composition and RoHS compliance as per Texas Instruments standards. Confirm the PDIP-20 package type matches the target PCB footprint requirements. Ensure the operating temperature range of 0°C to 70°C aligns with the environmental conditions of the intended application system.

Specialty Logic Selection Notes

Select this component when Schottky termination is preferred over resistor schemes to avoid increased power consumption or degraded output high levels. Consider the 16-bit array structure for efficient bus termination. Evaluate the low total capacitance and fast reverse recovery time for high-speed signal integrity requirements.

Specialty Logic Part Context

This part belongs to the SN74S series, utilizing Schottky technology for high-speed operation. It serves as a specialized passive interface component rather than an active logic gate. The NE4 designation specifies the plastic dual-in-line package variant with environmental compliance attributes defined by the manufacturer.

Specialty Logic FAQ

How does the SN74S1053 handle negative transients?

The diodes conduct current when the voltage reaches a negative value large enough to turn them on, thereby suppressing negative transients caused by transmission-line reflections.

What are the absolute maximum ratings for forward current?

The continuous forward current is 50 mA per terminal (170 mA total), while the repetitive peak forward current is 200 mA per terminal (1.2 A total).
