DESCRIPTION
74LVC322245A; 74LVCH322245A
The 74LVC(H)322245A 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 in a mixed 3.3 and 5 V environment. The 74LVC(H)322245A is a 32-bit transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The 74LVC(H)322245A features two output enable (nOE) inputs for easy cascading and two send or receive (nDIR) inputs for direction control. nOE controls the outputs so that the buses are effectively isolated. The 74LVC(H)322245A is designed with 30 series termination resistors in both HIGH and LOW output stages to reduce line noise. To ensure the high-impedance state during power-up or power-down, input nOE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. The 74LVCH322245A bus hold data inputs eliminates the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level (see Fig.2).
QUICK REFERENCE DATA Ground = 0 V; Tamb = 25 °C; tr = tf 2.5 ns. SYMBOL tPHL/tPLH CI CI/O CPD Note 1. CPD is used to determine the dynamic power dissipation (PD in µW). PD = CPD × VCC2 × fi + (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; (CL × VCC2 × fo) = sum of the outputs.
