DESCRIPTION
74LVC2245A
The 74LVC2245A 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. In 3-state operation, outputs can handle 5 V. These features allow the use of these devices as translators in a mixed 3.3 and 5 V environment. The 74LVC2245A is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The 74LVC2245A features an output enable (OE) input for easy cascading and a send/receive (DIR) input for direction control. OE controls the outputs so that the buses are effectively isolated. The 74LVC2245A is designed with 30 series termination resistors in both HIGH and LOW output stages to reduce line noise.
QUICK REFERENCE DATA GND = 0 V; Tamb = 25 C; tr = tf 2.5 ns. SYMBOL tPHL/tPLH 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. PARAMETER propagation delay An to Bn, Bn to An input capacitance power dissipation capacitance per buffer VCC = 3.3 V; notes 1 and 2 CONDITIONS CL = 50 pF; VCC = 3.3 V TYPICAL 3.6 4.0 13 ns pF pF UNIT
