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 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

DESCRIPTIONThe 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.

ABSOLUTE MAXIMUM RATINGS1, 2
NOTES: 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. 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 150°C. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.

RECOMMENDED OPERATING CONDITIONS
DC ELECTRICAL CHARACTERISTICS (3.3V 0.3V RANGE)
NOTES: All typical values are at VCC = 3.3V and Tamb = 25°C. This is the increase in supply current for each input at the specified voltage level other than VCC or GND This parameter is valid for any VCC between 0V and 1.2V with a transition time of up to 10msec. From VCC = 1.2V to VCC = 3.3V ± 0.3V a
transition time of 100μsec is permitted. This parameter is valid for Tamb = 25°C only. Unused pins at VCC or GND. ICCZ is measured with outputs pulled up to VCC or pulled down to ground. This is the bus hold overdrive current required to force the input to the opposite logic state.

DYNAMIC SWITCHING THRESHOLDDynamic 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.
