SN74ALVCHS162830A中文资料具有总线保持和三态输出的 18 通道、2.3V 至 3.6V 缓冲器数据手册TI规格书

描述 Description

This 1-bit to 2-bit address driver is designed for 2.3-V to 3.6-V VCC operation. Diodes to VCC have been added on the inputs to clamp overshoot. Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended. The outputs, which are designed to sink up to 12 mA, include series damping resistors to reduce overshoot and undershoot. The ALVCHS162830A is an improved version of the LVCHS162830 (non-A version) and has been optimized for lower power consumption and higher AC drive. Higher AC drive provides capability to drive loads with a faster edge rate. To ensure the high-impedance state during power up or power down, the output-enable (OE)\\ input should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
