NC7SZ57_V01中文资料安森美半导体数据手册PDF规格书

描述 Description

The NC7SZ57 and NC7SZ58 are universal configurable two−input

logic gates. Each device is capable of being configured for 1 of 5

unique two−input logic functions. Any possible two−input

combinatorial logic function can be implemented, as shown in the

Function Selection Table. Device functionality is selected by how the

device is wired at the board level. Figures 4 through 13 illustrate how

to connect the NC7SZ57 and NC7SZ58, respectively, for the desired

logic function. All inputs have been implemented with hysteresis.

The device is fabricated with advanced CMOS technology to

achieve ultra high speed with high output drive while maintaining low

static power dissipation over a broad VCC operating range. The device

is specified to operate over the 1.65 V to 5.5 V VCC operating range.

The input and output are high impedance when VCC is 0 V. Inputs

tolerate voltages up to 5.5 V independent of VCC operating range.
