74AVC16245 16-bit transceiver with direction pin 3.6 V tolerant 3-state Rev. 3 31 January 2013 Product data sheet 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 V through a pull-up resistor (Live Insertion). CC 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 Wide supply voltage range from 1.2 V to 3.6 V Complies with JEDEC standards: JESD8-7 (1.2 V to 1.95 V) JESD8-5 (1.8 V to 2.7 V) JESD8-1A (2.7 V to 3.6 V) CMOS low power consumption Input/output tolerant up to 3.6 V Dynamic Controlled Output (DCO) circuit dynamically changes output impedance, resulting in noise reduction without speed degradation Low inductance multiple VCC and GND pins to minimize noise and ground bounce Supports Live Insertion 3.
