DESCRIPTION 74AVC16245 The 74AVC16245 is a 16-bit transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The 74AVC16245 features two output enable inputs (nOE) for easy cascading and two send/receive inputs (nDIR) for direction control. Input nOE controls the outputs so that the buses are effectively isolated. This device can be used as two 8-bit transceivers or one 16-bit transceiver. This product is designed to have an extremely fast propagation delay and a minimum amount of power consumption. To ensure the high-impedance output state during power-up or power-down, input nOE should be tied to VCC through a pull-up resistor (live insertion). A DCO circuitry is implemented to supp...
