■COMPATIBLE WITH TTL OUTPUTS: VIH = 2V (MIN), VIL = 0.8V (MAX)
■POWER DOWN PROTECTION ON INPUTS
■OPERATING VOLTAGE RANGE: VCC (OPR) = 4.5V to 5.5V
■IMPROVED LATCH-UP IMMUNITY
DESCRIPTION
The 74V1T05 is an advanced high-speed CMOS SINGLE INVERTER (OPEN DRAIN) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.
The internal circuit is composed of 3 stages including buffer output, which provide high noise immunity and stable output.

This device can, with an external pull-up resistor, be used in wired AND configuration. This device can also be used as a led driver in any other application requiring a current sink.
Power down protection is provided on input and 0 to 7V can be accepted on input with no regard to the supply voltage. This device can be used to interface 5V to 3V.
