ON Semiconductor MC74VHCT245ADTG Octal Bus Transceiver

The MC74VHCT245ADTG from ON Semiconductor is a high-speed octal bus transceiver designed to address the needs for efficient and reliable data transfer in modern electronic systems. This integrated circuit is a member of the VHCT family and is particularly suitable for driving bus lines or buffer memory address registers thanks to its bidirectional interface.

Constructed with advanced silicon-gate CMOS technology, the MC74VHCT245ADTG offers the high-speed operation of LSTTL combined with the low power consumption of standard CMOS integrated circuits. This makes it an excellent choice for interfacing with different logic levels, ranging from 3.3V to 5V, allowing for flexible integration into mixed-voltage systems.

The device features an octal non-inverting bus transceiver with 3-state outputs, which means that each of the eight channels can be independently controlled. The 3-state outputs allow for connection to a bus-oriented system without the risk of bus contention. This is especially useful in multiplexed bus applications where output enable signals are required.

The MC74VHCT245ADTG operates at a voltage range of 4.5V to 5.5V, ensuring compatibility with TTL power supply levels. Its inputs are TTL voltage level compatible, which simplifies the design process by allowing direct interfacing with TTL logic without the need for additional level shifting components.

The transceiver's package is a TSSOP-20, which stands for Thin Shrink Small Outline Package with 20 leads. This compact form factor makes it suitable for space-constrained applications while still providing robust performance. Furthermore, the device is characterized for operation from -40°C to +85°C, guaranteeing functionality across a wide range of environmental conditions.

Key features of the MC74VHCT245ADTG include:

• High-Speed CMOS Technology
• TTL-Compatible Input Levels
• Octal Bidirectional Transceiver with 3-State Outputs
• Operating Voltage Range of 4.5V to 5.5V
• Low Power Consumption
• Industrial Operating Temperature Range of -40°C to +85°C
