The TC74VHCT367AFT from Toshiba is a high-speed CMOS Hex Bus Buffer with three-state outputs. It is designed for use in bus-oriented applications where high speed and low power consumption are required. The device is pin-compatible with bipolar LS TTL logic, making it easy to upgrade existing systems.

Applications:

• Memory addressing
• Data bus buffering
• Address decoding
• Input/output port expansion
• Logic level translation

Features:

• High-speed operation: tpd = 5.2 ns (typ.) at VCC = 5V
• Low power consumption: ICC = 4.0 μA (max) at Ta = 25°C
• Wide operating voltage range: VCC = 4.5V to 5.5V
• TTL compatible input thresholds
• Three-state outputs for bus interfacing
• Output enable control for each buffer

Benefits:

• Fast data transmission for improved system performance.
• Energy-efficient operation, suitable for power-sensitive applications.
• Direct replacement for LS TTL devices, simplifying system upgrades.
• Easy integration with TTL logic circuits.
• Allows for multiple devices to share a common bus without contention.
• Provides flexibility in enabling and disabling individual buffer sections.

Additional Details:

The TC74VHCT367AFT contains six independent buffers with three-state outputs. The outputs can be enabled or disabled using the output enable inputs (OE1 and OE2). When the output enable input is high, the outputs are in a high-impedance state. The device is available in a TSSOP package, making it suitable for high-density PCB layouts. The operating temperature range is -40°C to +85°C. The TTL-compatible input thresholds ensure reliable operation with TTL logic signals.
