M54HC51数据手册ST中文资料规格书

描述 Description

The M54/74HC51 is a high speed CMOS DUAL 2 WIDE-2 INPUT AND/OR INVERT GATE fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. It contains a 2-WIDE 2-INPUT AND-OR-INVERT GATE and a 2-WIDE 3-INPUT AND-OR-INVERT GATE.\r
\r
The internal circuit is composed of 3 stages (2-INPUT) or 5 stages (3-INPUT) including buffered output, which gives high noise immunity and a stable output.All inputs are equipped withprotection circuits against static discharge and transient excess voltage.
