August 1999 HIGH SPEED:tPD =3.2ns (TYP.)at VCC =5V LOWPOWER DISSIPATION:
ICC =2 μA (MAX.)atTA =25oC COMPATIBLEWITH TTL OUTPUTS:
VIH =2V (MIN), VIL= 0.8V(MAX) POWERDOWN PROTECTIONON INPUTS OPERATINGVOLTAGERANGE:
VCC (OPR)= 4.5Vto 5.5V PIN AND FUNCTION COMPATIBLE WITH SERIES05 IMPROVEDLATCH-UP IMMUNITY LOWNOISE: VOLP= 0.8V (Max.)
DESCRIPTION
The 74VHCT05Ais an advanced high-speed
CMOS OPEN DRAIN HEX INVERTER fabricated
with sub-micron silicon gate and double-layer
metal wiringC2 MOStechnology.
The internal circuitis composed of3 stages
including buffer output, which provides high noise
immunity and stable output.
Power down protectionis provided on all inputs
and0to 7V can be acceptedon inputs with no
regardto the supply voltage. This device canbe
usedto interface5Vto 3V.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
