3V 16-bit bus transceiver (3-State) 74ALVT16646 FEATURES • 16-bit universal bus interface • 5V I/O Compatible • 3-State buffers • Output capability: +64mA/-32mA • TTL input and output switching levels • Input and output interface capability to systems at 5V supply • Bus-hold data inputs eliminate the need for external pull-up • Live insertion/extraction permitted • No bus current loading when output is tied to 5V bus • Power-up reset • Power-up 3-State • Latch-up protection exceeds 500mA per JEDEC Std 17 • ESD protection exceeds 2000V per MIL STD 883 Method 3015 and 200V per Machine Model resistors to hold unused inputs DESCRIPTION The 74ALVT16646 is a high-performance BiCMOS product designed for VCC operation at 2.
5V or 3.
3V with I/O compatibility up to 5V.
This device is a 16-bit transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions.
The control function implementation minimizes external timing requirements.
The device features an Output Enable (OE) input for easy cascading and a Direction (DIR) input for direction control.
Data on the A or B bus is clocked into the registers on the Low to High transition of the appropriate clock (CPAB or CPBA).
The select-control (SAB and SBA) inputs can multiplex stored and real-time (transparent mode data).
