SN74LVCH322244A 具有三态输出的 32 位缓冲器/驱动器
SN74LVCH322244A 描述
This 32-bit buffer/driver is designed for 1.65-V to 3.6-V VCC operation.
The SN74LVCH322244A is designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.
The device can be used as eight 4-bit buffers, four 8-bit buffers, two 16-bit buffers, or one 32-bit buffer. It provides true outputs and symmetrical active-low output-enable (OE)\ inputs.
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.
The outputs, which are designed to sink up to 12 mA, include equivalent 26-
resistors to reduce overshoot and undershoot
