3.3V Quad buffer (3-State)
Product specification
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
• 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
DESCRIPTION
The LVT126 is a high-performance BiCMOS product designed for
VCC operation at 3.3V.
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.
