SN74LVCH162244A 具有三态输出的 16 位缓冲器/驱动器
SN74LVCH162244A 描述
This 16-bit buffer/driver is designed for 1.65-V to 3.6-V VCC operation.
The SN74LVCH162244A is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. It provides true outputs and symmetrical active-low output-enable (OE)\ inputs.
The outputs, which are designed to sink up to 12 mA, include equivalent 26-
resistors to reduce overshoot and undershoot.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.
This device is fully specified for partial-power-down applications using Ioff
