2 / 14 page 2004 Mar 22 2 Philips Semiconductors Product specification Quad 2-input NAND gate (open drain) 74LVC38A 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 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. Notes 1. CPD is used to determine the dynamic power dissipation (PD in µW). PD =CPD × VCC2 × fi × N+ Σ(CL × VCC2 × 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; Σ(CL × VCC2 × fo) = sum of the outputs. 2. The condition is VI = GND to VCC.
