74VHCT245AMTC

The 74VHCT245AMTC from On Semiconductor is an advanced high-speed CMOS octal bus transceiver. It is designed for bidirectional asynchronous communication between data busses, with the direction of data transmission determined by the Transmit/Receive (T/R) input. The device features 3-state outputs, which can be enabled or disabled using the Output Enable (OE) input, allowing for effective isolation of data busses.

This buffer/line driver operates at high speeds, with a typical propagation delay of 5.4 ns at 5V. It supports a supply voltage range of 4.5V to 5.5V and operates within an ambient temperature range of -40°C to 85°C. The device exhibits low power dissipation, with a maximum quiescent current of 4 μA at 25°C.

Designed for compatibility, it is pin and function compatible with the 74HCT245. The 74VHCT245AMTC is supplied in a 20-TSSOP package, suitable for surface mounting. Protection circuits are integrated to ensure that 0V to 5.5V can be applied to input and output pins without regard to the supply voltage, preventing device destruction due to mismatched voltages. This makes it suitable for interfacing 5V to 3V systems.

Key specifications include a logic type of Buffer, Non-Inverting, with 8 bits per element and a single element. The output current is rated at 8mA for both high and low states. The device is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1.
