Resistors in B Outputs

74LCXZ2245
Low Voltage Bidirectional Transceiver
with 5V Tolerant Inputs and Outputs
and 26: Series Resistors in B Outputs
General Description
The LCXZ2245 contains eight non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus ori-
ented applications. The device is designed for low voltage
(2.7V and 3.3V) V
CC
applications with capability of interfac-
ing to a 5V signal environment. The T/R input determines
the direction of data flow through the device. The OE input
disables both the A and B ports by placing them in a high
impedance state. The 26
:
series resistor in the B Port out-
put helps reduce output overshoot and undershoot.
The LCXZ2245 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
When V
CC
is between 0 and 1.5V, the LCXZ2245 is on the
high impedance state during power up or power down. This
places the outputs in the high impedance (Z) state prevent-
ing intermittent low impedance loading or glitching in bus
oriented applications.

Note 1:
To ensure the high-impedance state during power up or down, OE
should be tied to V
CC
through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.

硬件寄存器是如何工作的
大多数时候,寄存器都保持在稳定的状态,产生的输出等于它的当前状态。信号沿着寄存器前面的组合逻辑传播,这时,产生了一个新的寄存器输入。但只要时钟是地电位的,寄存器的输出就会保持不变。 ......
