ORDER CODES : 74LVX27M 74LVX27T power dissipation. The internal circuit is composed of 3 stages including buffer output, which provides high noise immunity and stable output. Power down protection is provided on all inputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
DESCRIPTION The 74LVX27 is an advanced high-speed CMOS TRIPLE 3-INPUT NOR GATE fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It has similar high speed performance of equivalent Bipolar Schottky TTL combined with true CMOS low
