74VHC32_99 데이터시트 - STMicroelectronics

DESCRIPTION
The 74VHC32 is an advanced high-speed CMOS QUAD 2-INPUT OR GATE fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.
The internal circuit is composed of 2 stages including buffer output, which provide 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.

■ HIGH SPEED: tPD = 3.8 ns (TYP.) at VCC = 5V
■ LOW POWER DISSIPATION:
   ICC =2 µA (MAX.) at TA = 25 °C
■ HIGH NOISE IMMUNITY:
   VNIH = VNIL = 28% VCC (MIN.)
■ POWERDOWN PROTECTIONON INPUTS
■ SYMMETRICAL OUTPUT IMPEDANCE:
   |IOH| = IOL = 8 mA (MIN)
■ BALANCEDPROPAGATIONDELAYS: tPLH ≅ tPHL
■ OPERATING VOLTAGERANGE:
   VCC (OPR)= 2V to 5.5V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 32
■ IMPROVED LATCH-UP IMMUNITY
■ LOW NOISE: VOLP = 0.8V(Max.)
