TC74VHC367FTEL

Overview

The TC74VHC367FTEL is a hex bus buffer fabricated with silicon gate C2MOS technology. It contains six non-inverting buffers controlled by two enable inputs (1G and 2G). Outputs enter a high-impedance state when enabled inputs are held high. The device supports a supply voltage range of 2.0 V to 5.5 V, with input voltages tolerating up to 5.5 V regardless of the supply level. Propagation delay is typically 3.8 ns at 5 V. Quiescent current is 4 μA maximum at 25°C. Noise immunity is defined as 28% of VCC minimum.

Feature Summary

• Advanced high-speed operation comparable to Bipolar Schottky TTL while maintaining CMOS low power dissipation
• Input protection circuit allows 0 to 5.5 V application without regard to supply voltage
• Power down protection provided on all inputs to prevent device destruction from mismatched voltages

Applications

• Interfacing 5 V systems to 3 V systems
• Connecting two supply systems such as battery backup
• General electronics applications including computers and office equipment

Procurement Notes

Verify the specific package suffix against the datasheet to confirm physical dimensions and weight. Ensure the ordering code matches the required TSSOP or other variant. Confirm RoHS compliance status directly with Toshiba Semiconductor and Storage representatives prior to procurement. Review the restrictions on product use for unintended applications.

Selection Notes

Select this component for designs requiring hex bus buffering with independent control groups. The dual enable inputs allow flexible partitioning of the six buffers. Verify that the 5.5 V input tolerance meets system requirements for interfacing different voltage domains. Check propagation delay specifications against the target clock frequencies in the specific operating temperature range.

Part Context

This part belongs to the TC74VHC367/368 series of advanced high-speed CMOS logic devices. It is functionally compatible with the 74ALS367/368 standard. The FTEL designation indicates a specific surface-mount package variant within the broader family of hex bus buffers produced by Toshiba Semiconductor and Storage.
