74LVCH32245A

74LVCH32245A 32-bit bus transceiver with direction pin; 5 V tolerant; 3-state Rev. 03 — 20 August 2007 Product data sheet 1. General description The 74LVCH32245A 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. Bus hold on data inputs eliminates the need for external pull-up resistors to hold unused inputs. 2.

Note that control inputs do not have a bus hold circuit. The specified sustaining current at the data input holds the input below the specified VI level. The specified overdrive current at the data input forces the data input to the opposite input state. 74LVCH32245A_3 © NXP B.V. 2007. All rights reserved.
