74AVC16245屬于集成電路（IC）的緩沖器驅動器接收器收發(fā)器。由安世半導體(中國)有限公司制造生產的74AVC16245緩沖器，驅動器，接收器，收發(fā)器邏輯緩沖器、驅動器、接收器和收發(fā)器允許隔離對某個電路的邏輯信號的訪問，以用于另一電路。緩沖器將其輸入信號（不變或反相）傳遞到其輸出，并可能用于清除弱信號或驅動負載。在布爾邏輯仿真器中，緩沖器主要用于增加傳播延遲。邏輯接收器和收發(fā)器允許在數(shù)據(jù)總線之間進行隔離通信。

1. General description

The 74AVC16245 is a 16-bit transceiver featuring non-inverting 3-state bus compatible

outputs in both send and receive directions. The device features two output enable inputs

(nOE) for easy cascading and two send/receive inputs (nDIR) for direction control.

Inputs nOE control the outputs so that the buses are effectively isolated. This device can

be used as two 8-bit transceivers or one 16-bit transceiver.

The 74AVC16245 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, tie pins nOE

to VCC through a pull-up resistor (Live Insertion).

A Dynamic Controlled Output (DCO) circuitry is implemented to support termination line

drive during transient (see Figure 4 and Figure 5)

2. Features and benefits
