74HCT03
74HCT03 is Quad 2-input NAND gate manufactured by NXP Semiconductors.
FEATURES
- Level shift capability
- Output capability: standard (open drain)
- ICC category: SSI GENERAL DESCRIPTION
The 74HC/HCT03 are high-speed Si-gate CMOS devices and are pin patible with low power Schottky TTL (LSTTL). They are specified in pliance with JEDEC standard no. 7A. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns
74HC/HCT03
The 74HC/HCT03 provide the 2-input NAND function. The 74HC/HCT03 have open-drain N-transistor outputs, which are not clamped by a diode connected to VCC. In the OFF-state, i.e. when one input is LOW, the output may be pulled to any voltage between GND and VOmax. This allows the device to be used as a LOW-to-HIGH or HIGH-to-LOW level shifter. For digital operation and OR-tied output applications, these devices must have a pull-up resistor to establish a logic HIGH level.
TYPICAL SYMBOL t PZL/ t PLZ CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD × VCC2× fi + ∑ (CL × VCC2 × fo) + ∑ (VO2/RL) × duty factor LOW, where: fi = input frequency in MHz fo = output frequency in MHz VO = output voltage in V CL = output load capacitance in p F VCC = supply voltage in V RL = pull-up resistor in MΩ ∑ (CL × VCC2 × fo) = sum of outputs ∑ (VO2/RL) = sum of outputs 2. For HC the condition is VI = GND to VCC For HCT the condition is VI = GND to VCC
