SN7416DR

SN7416DR Description

The SN7416DR from Texas Instruments is a hex inverter buffer/driver IC belonging to the 7400 series, designed for high-voltage interface applications. Packaged in a 14-SOIC surface-mount format, it features six independent inverters with open-collector outputs, enabling direct interfacing with higher-voltage circuits (up to 15V). Operating within a 4.75V–5.25V supply range, it delivers a maximum propagation delay of 23ns at 5V/15pF, ensuring reliable performance in digital logic systems. The device is RoHS3 compliant and rated for industrial temperatures (0°C to 70°C), making it suitable for a broad range of environments.

SN7416DR Features

• Logic Type: Hex inverter with open-collector outputs for flexible voltage-level shifting.
• High Noise Immunity: Input thresholds of 0.8V (Low) and 2V (High) ensure robust operation in noisy environments.
• Low Power Consumption: Optimized for 5V TTL systems, balancing speed and efficiency.
• Surface-Mount Design: 14-SOIC package (Tape & Reel) enables compact PCB integration.
• Reliable Performance: MSL1 (Unlimited) moisture sensitivity and REACH unaffected compliance.
• Wide Compatibility: Backward-compatible with legacy 7400-series logic families.

SN7416DR Applications
