Texas Instruments High-Performance Analog Universal Bus Functions SN74ALVCHR16269ALR

The SN74ALVCHR16269ALR is a 12-bit to 24-bit registered bus exchanger designed for operation within a voltage range of 1.65 V to 3.6 V. This device is part of the Texas Instruments Widebus,Ñ¢ family and features three-state outputs, making it suitable for applications requiring multiplexing or demultiplexing of data between two ports and a single port. It supports a maximum propagation delay of 5.2 ns at 3.3 V and can drive outputs with a current of up to 24 mA. The device includes built-in bus-hold circuitry that maintains valid logic levels on unused inputs, eliminating the need for external pull-up or pull-down resistors. Additionally, it offers robust ESD protection exceeding JESD 22 standards, with ratings of 2000 V for the human-body model and 200 V for the machine model. The SN74ALVCHR16269ALR is particularly effective as an interface between synchronous DRAMs and high-speed microprocessors, ensuring synchronous data transactions controlled by clock and enable signals. It is available in multiple package options, including SSOP and TSSOP, and operates within a temperature range of -40¬8C to 85¬8C.
