MM74HC05中文资料Hex Inverter (Open Drain)数据手册TI规格书

描述 Description

General Description
The MM54HC05/MM74HC05 are logic functions fabricated by using advanced silicon-gate CMOS technology, which provides the inherent benefits of CMOSÐlow quiescent power and wide power supply range. These devices are also functionally and pin-out compatible with standard DM54LS/DM74LS logic families. The MM54HC05/MM74HC05 open drain Hex Inverter requires the addition of an external resistor to perform a wire-NOR function.
All inputs are protected from static discharge damage by internal diodes to VCC and ground.

特性 Features

■ Open drain for wire-NOR function
■ Fanout of 10 LS-TTL loads
■ Typical propagation delays:
   tPZL (with 1 kX resistor) 8 ns
   tPLZ (with 1 kX resistor) 13 ns
■ Low input current: 1 μA maximum
