Texas Instruments SN74LV161284 19-Bit Bus Interface SN74LV161284DGGR

The SN74LV161284 is a 19-bit bus interface designed for operation within a supply voltage range of 4.5 V to 5.5 V. It facilitates asynchronous two-way communication between data buses, featuring eight bidirectional data lines. The device supports IEEE Std 1284-I and IEEE Std 1284-II specifications, making it suitable for parallel peripheral interfaces. The SN74LV161284 includes integrated 1.4-k,Ѷ pullup resistors on all open-drain outputs, which simplifies PCB design by eliminating the need for discrete resistors. It has a flow-through architecture that optimizes layout efficiency. The device is equipped with five drivers and four receivers, with dedicated lines for HOST LOGIC and PERI LOGIC. The output drive mode can be configured via a high-drive control pin, allowing for either totem-pole or open-drain configurations. The device's latch-up performance exceeds 250 mA per JEDEC 17, and it offers robust ESD protection, exceeding 4000 V for the human-body model. The operating temperature range is specified from -40¬8C to 85¬8C, making it suitable for various applications.
