Toshiba 8-Bit Non-Inverting CMOS TTL Bus Transceiver 20-Pin TSSOP 74VHCT245AFT

Toshiba 74VHCT245AFT is a high-speed 8-bit bus transceiver using advanced silicon gate C2MOS technology. It provides non-inverting two-way asynchronous communication between data buses, enabling efficient data transmission control with a DIR input to manage data direction and an enable input (G) to disable the device and isolate the buses.

The device maintains TTL compatible input voltage levels and CMOS/TTL output voltage levels, making it suitable for interfacing between 3.3 V and 5 V systems. It achieves high-speed operation with a maximum propagation delay of 8.7 ns and low power dissipation, consuming a maximum ICC of 2.0 μA at 25°C.

The transceiver operates reliably over a wide temperature range from -40°C to 125°C, which suits industrial, automotive, and commercial electronics applications. Its package type is a 20-pin Thin Shrink Small Outline Package (TSSOP), offering compact size with dimensions of 6.5 mm length and 1 mm height.

The device features balanced propagation delays, low noise output performance (VOLP max 1.0 V), and power-down protection on all inputs and outputs to prevent device damage. It is function and pin compatible with the standard 74 series 245 logic family, facilitating easy integration into existing systems.

Compliant with AEC-Q100 automotive standards, the 74VHCT245AFT is ideal for automotive electronics where high reliability and extended temperature operation are critical. The device supports two-way asynchronous communication between data buses with 8-bit channel capability.

Direction control and enable pins provide flexible data flow and bus isolation. TTL compatible input and CMOS/TTL output voltage levels. Wide operating temperature from -40°C to 125°C for harsh environments. Low power C2MOS technology supports high-speed operation with minimal power consumption.

Pin and function compatible with 74 series 245 logic devices for easy replacement. Power-down protection prevents latch-up and device destruction. Compact 20-pin TSSOP package with reduced footprint. Compliant with automotive-grade AEC-Q100 standards.

This bus transceiver model is widely used in industrial and automotive systems for reliable data bus communication and signal level management. It is suitable for electronic design engineers and system integrators requiring robust and high-performance logic components.
