Quad 2-input NAND gate (open drain)
FEATURES * 5 V tolerant inputs for interfacing with 5 V logic * Wide supply voltage range from 1.2 to 3.6 V * CMOS low power consumption * Direct interface with TTL levels * Open-drain outputs * Inputs accept voltages up to 5.5 V * Complies with JEDEC standard no. 8-1A * Specified from -40 to +85 C and -40 to +125 C. DESCRIPTION
74LVC38A
The 74LVC38A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. Inputs can be driven from either 3.3 or 5 V devices. This feature allows the use of these devices as translators in a mixed 3.3 and 5 V environment. The 74LVC38A provides the 2-input NAND function. The outputs of the 74LVC38A devices are open drain and can be connected to other open-drain outputs to implement active-LOW wired-OR or active-HIGH wired-AND functions.
QUICK REFERENCE DATA GND = 0 V; Tamb = 25 C; tr = tf 2.5 ns. SYMBOL tPZL tPLZ CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD x VCC2 x fi x N + (CL x VCC2 x fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; N = total load switching outputs; (CL x VCC2 x fo) = sum of the outputs. 2. The condition is VI = GND to VCC.
