The document describes the features and characteristics of a product called SCBS258M. The product belongs to the Texas Instruments Widebus family and has equivalent 22-Ω series resistors, eliminating the need for external resistors. It supports mixed-mode signal operation with 5V input and output voltages and 3.3V VCC. It also supports unregulated battery operation down to 2.7V. The product has low output ground bounce, Ioff and power-up 3-state support hot insertion, bus hold on data inputs eliminating the need for external pullup/pulldown resistors, distributed VCC and GND pins minimizing high-speed switching noise, flow-through architecture optimizing PCB layout, latch-up performance exceeding 500mA, and ESD protection exceeding 2000V.
The SN54LVTH162244 and SN74LVTH162244 devices are 16-bit buffers and line drivers designed for low-voltage (3.3-V) operation, capable of providing a TTL interface to a 5-V system environment. These devices can be configured as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer, featuring true outputs and symmetrical active-low output-enable inputs.
