SN74LVT16245BDLR - 3.3-V ABT 16-Bit Bus Transceivers With 3-State Outputs

The SN74LVT16245BDLR is a high-performance, BiCMOS product designed by Texas Instruments for bus interface applications in 3.3V systems. This 16-bit transceiver features two separate 8-bit buses (A and B) that allow for bidirectional data flow. It is particularly suitable for driving high-capacitive loads and provides improved signal integrity at high frequencies.

With its low-voltage TTL (LVTTL) logic level, the SN74LVT16245BDLR is optimized for use in mixed 3.3V/5V systems. It incorporates bus-hold data inputs which eliminate the need for external pull-up or pull-down resistors, simplifying board design and reducing board space requirements.

The device comes in a compact 48-pin SSOP (Shrink Small-Outline Package) that is well-suited for space-constrained applications. The SN74LVT16245BDLR operates over a broad temperature range, making it a versatile choice for industrial and commercial applications.

Key Features:

• Bidirectional Data Flow: With two separate 8-bit buses, the device supports simultaneous bidirectional data transmission.
• 3-State Outputs: The transceiver features 3-state outputs, which can be placed in a high-impedance state to disconnect the bus or to enable multiple devices to share the same bus.
• Bus-Hold Data Inputs: The integrated bus-hold circuitry prevents floating inputs and undefined logic levels without the need for external resistors.
• Low Power Consumption: This device is designed for low power operation, helping to reduce the overall power consumption of the system.
• Compatibility: It is compatible with mixed-mode signal operation, allowing it to interface with 5V logic signals while operating at a 3.3V supply.
• Wide Operating Temperature Range: The transceiver is reliable over an extended temperature range, which is ideal for harsh-environment applications.

The SN74LVT16245BDLR is an excellent choice for designers looking for a robust, high-speed transceiver capable of interfacing between 3.3V and 5V logic families. Its advanced features and small package size make it an efficient solution for data bus transmission and buffering in a wide array of electronic systems, including computing, networking, and telecommunications equipment.
