74AVCH16245
General description
The 74AVCH16245 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 74AVCH16245 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, pins nOE should be tied to VCC through a pull-up resistor (Live Insertion).
A Dynamic Controlled Output (DCO) circuitry is implemented to support termination line drive during transient.
The 74AVCH16245 has active bus-hold circuitry to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors.
Features
- Wide supply voltage range from 1.2 to 3.6 V
- Complies with JEDEC standard no. 8-1A/5/7
- 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
- All inputs have bus-hold.
