Product Overview: 74HCT245D by NXP Semiconductors

The 74HCT245D is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). It is fabricated with silicon gate C2MOS technology and designed by NXP Semiconductors, a leader in high-performance mixed-signal electronics.

Key Features

• Octal Bus Transceiver: The 74HCT245D features eight non-inverting bidirectional buffers and can be used as an input or output buffer when operated in the bus-enabled mode.
• 3-State Outputs: This device includes 3-state outputs that are controlled by the output enable input (OE). The 3-state outputs allow for connection to a bus without interfering with other components on the bus.
• Wide Operating Voltage: It operates at a voltage range of 4.5 V to 5.5 V, which makes it suitable for interfacing with 5V logic levels in mixed-voltage systems.
• High Noise Immunity: The 74HCT245D is characterized by high noise immunity and low power consumption, typical of CMOS integrated circuits.
• Compatibility: The input levels are compatible with TTL output levels, which allows for direct interfacing with TTL logic without the need for level shifters.

Applications

The 74HCT245D is versatile and can be used in a wide range of applications, including:

• Bus interface or bus exchange in multi-bus designs
• Data communication and signal processing
• Memory buffering and data storage
• I/O port expansion

Physical Packaging

The device is provided in a 20-pin SOIC package, which is suitable for surface-mounted technology (SMT) and offers a space-saving solution for PCB designs.
