NC7SZ57屬于集成電路（IC）的門反相器-多功能可配置。由安森美半導體公司制造生產的NC7SZ57門和反相器 - 多功能，可配置可配置邏輯柵極系列產品能以與標準邏輯柵極類似的方式，對單個邏輯信號執(zhí)行基本邏輯運算，但并非局限于一個特定功能（例如 AND、NAND 等）。它們通常在內部使用少量邏輯門來實現(xiàn)，經過選擇和互連后，以便通過選擇操作數(shù)據(jù)所應用的輸入以及任何未使用的輸入在驅動后的邏輯狀態(tài)，來配置所實現(xiàn)的整體邏輯功能。

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.
