74LVT16244B
FEATURES
• 16-bit bus interface
DESCRIPTION
The 74LVT16244B is a high-performance BiCMOS product
designed for V operation at 3.3V.
CC
• 3-State buffers
This device is a 16-bit buffer and line driver featuring non-inverting
3-State bus outputs. The device can be used as four 4-bit buffers,
two 8-bit buffers, or one 16-bit buffer.
• 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
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
and 200V 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 150°C.
3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
