74LVC32245A
32-bit bus transceiver with direction pin; 5 V tolerant; 3-state
Rev. 01 -- 20 August 2007 Product data sheet
1. General description
The 74LVC32245A is a 32-bit transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The device features four output enable (nOE) inputs for easy cascading and four send/receive (nDIR) inputs for direction control. Pin nOE controls the outputs so that the buses are effectively isolated. Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to the outputs. These features allow the use of these devices in mixed 3.3 V and 5 V applications. To ensure the high-impedance state during power-up or power-down, pin 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.

Typical values are measured at Tamb = 25 C and VCC = 1.2 V, 2.7 V, and 3.3 V respectively. tpd is the same as tPLH and tPHL. ten is the same as tPZL and tPZH. tdis is the same as tPLZ and tPHZ. Skew between any two outputs of the same package switching in the same direction. This parameter is guaranteed by design. 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 = number of inputs switching (CL x VCC2 x fo) = sum of the outputs.
