The M74HC245-1FP is a high-speed CMOS octal bus transceiver fabricated with silicon gate C2MOS technology. It achieves high-speed operation similar to equivalent Schottky TTL while maintaining the CMOS low power dissipation. The M74HC245-1FP is an octal transceiver featuring non-inverting outputs. This device is designed for asynchronous two-way communication between data buses.

Applications:

• Memory Interface
• Microprocessor Systems
• Data Bus Isolation
• Peripheral Control

Features:

• High Speed: tpd = 13ns (typ.) at VCC = 5V
• Low Power Dissipation: ICC = 4µA (max.) at TA = 25°C
• High Noise Immunity: VNIH = VNIL = 28 % VCC (min.)
• Output Drive Capability: 15 LSTTL Loads
• Symmetrical Output Impedance: |IOH| = IOL = 6mA (min.)
• Balanced Propagation Delays: tPLH ≈ tPHL
• Wide Operating Voltage Range: VCC (opr) = 2V to 6V
• Pin and Function Compatible with 74LS245

Benefits:

• Enables efficient data transmission between buses.
• Reduces power consumption in battery-powered applications.
• Provides stable operation in noisy environments.
• Facilitates interfacing with various TTL-based systems.
• Ensures reliable signal propagation.
• Allows for flexibility in power supply design.
• Simplifies integration with existing designs.

Additional Details:

The M74HC245-1FP is supplied in a 20-lead plastic dual in-line package (DIP20) and a small outline integrated circuit (SOIC20). The direction of data transmission is determined by the DIR input. The enable input (OE) disables the device so that the buses are effectively isolated. When OE is high, both output ports are in a high-impedance state.
