® 74V1T03 SINGLE 2-INPUT OPEN DRAIN NAND GATE PRELIMINARY DATA s s s s s s HIGH SPEED: tPD = 7 ns (TYP.) at VCC = 5V LOW POWER DISSIPATION: ICC = 1 µA (MAX.) at TA = 25 oC 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 S (SOT23-5L) C (SC-70) ORDER CODE: 74V1T03S 74V1T03C 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 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. DESCRIPTION The 74V1T03 is an advanced high-speed CMOS SINGLE 2-INPUT OPEN DRAIN NAND GATE 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.
