SOP 74VHCT03AMTR TSSOP 74VHCT03ATTR DESCRIPTIONThe 74VHCT03A is an advanced high-speedCMOS QUAD 2-INPUT OPEN DRAIN NAND regard to the supply voltage. This device can be GATE fabricated with sub-micron silicon gate and used to interface 5V to 3V since all inputs are double-layer metal wiring C2MOS technology. equipped with TTL threshold. The internal circuit is composed of 3 stages All inputs and outputs are equipped with including buffer output, which provides high noise protection circuits against static discharge, giving immunity and stable output. them 2KV ESD immunity and transient excess This device can, with an external pull-up resistor, voltage. be used in wired AND configuration. This devicecan also be used as a led driver and in any otherapplication requiring a current sink.Power down protection is provided on all inputsand 0 to 7V can be accepted on inputs with no Figure 1: Pin Connection And IEC Logic Symbols Rev. 3 December 2004 1/11 74VHCT03A Figure 2: Input Equivalent Circuit Table 2: Pin Description PIN N°
