74ALVT16245
FEATURES
* 16-bit bidirectional bus interface * 5V I/O Compatible * 3-State buffers * Output capability: +64mA/-32mA * TTL input and output switching levels * Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
DESCRIPTION
The 74ALVT16245 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.
* Live insertion/extraction permitted * Power-up 3-State * No bus current loading when output is tied to 5V bus * Latch-up protection exceeds 500mA per JEDEC Std 17 * ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 400V per Machine Model

NOTES: 1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150C. 3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.

DYNAMIC SWITCHING THRESHOLD
Dynamic switching threshold is the change in VIH and VIL when the device is operated in various switching and output loading conditions. The cause of this variation is due to extra load placed on internal circuit structures. VIHD and VILD are measures of the dynamic switching threshold. VIHD is the input high switching level when the device is heavily loaded. VILD is the input low switching level when the device is heavily loaded.
