The SN74ALS667NSRG4 from Texas Instruments is a high-performance, octal bus transceiver featuring non-inverting 3-state bus-compatible outputs in a 20-pin package. This integrated circuit is designed for asynchronous communication between data buses. The control-function implementation minimizes external timing requirements.

The device allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated. The SN74ALS667NSRG4 is characterized for operation from 0°C to 70°C, making it suitable for commercial applications.

Key Features:

• Octal Bidirectional Transceiver with 3-state outputs
• Non-inverting bus-compatible outputs
• Direct bus connection when high-impedance state is not needed
• Wide operating temperature range (0°C to 70°C)
• Designed specifically for driving heavy loads
• Low power consumption
• Improved latch-up immunity

Applications:

• Bus Interface / Transceiver in Microprocessor Systems
• Memory Switching
• Data Communication
• Networking Systems
• Peripheral Drivers

The SN74ALS667NSRG4 is manufactured using Texas Instruments' advanced low-power Schottky (ALS) technology, which combines the speed of Schottky TTL with the low power consumption of standard CMOS technology. The device's packaging and temperature range make it ideal for a wide range of applications, from industrial to consumer electronics. With its robust design and proven performance, the SN74ALS667NSRG4 is a reliable choice for designers who require a high-quality bus transceiver for their digital interfacing needs.
