3.3V Quad buffer (3-State)
74LVT126
FEATURES
• Quad bus interface
• 3-State buffers
• Output capability: +64mA/-32mA
• TTL input and output switching levels
• Input and output interface capability to systems at 5V supply
DESCRIPTION
The LVT126 is a high-performance BiCMOS product designed for
operation at 3.3V.
V
CC
This device combines low static and dynamic power dissipation with
high speed and high output drive.
The 74LVT126 device is a quad buffer that is ideal for driving bus
lines. The device features four Output Enables (OE0, OE1, OE2,
OE3), each controlling one of the 3-State outputs.
• Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
• Live insertion/extraction permitted
• No bus current loading when output is tied to 5V bus
• 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

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.
