1. General description
The 74ALVT16240 is a high-performance BiCMOS device designed for V
CC
operation at
2.5 V or 3.3 V with I/O compatibility up to 5 V.
The 74ALVT16240 is an inverting 16-bit buffer that is ideal for driving bus lines. The device
features four output enable inputs (1OE, 2OE, 3OE, 4OE), each controlling four of the
3-state outputs.
2. Features
a73 5 V I/O compatible
a73 Live insertion and extraction permitted
a73 3-state buffers
a73 Power-up 3-state
a73 Output capability: +64 mA and −32 mA
a73 Latch-up protection:
a78 JESD 78 exceeds 500 mA
a73 Electrostatic discharge protection:
a78 MIL STD 883 method 3015: exceeds 2000 V
a78 Machine model: exceeds 200 V
a73 Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs
a73 16-bit bus interface
a73 TTL input and output switching levels
a73 Input and output interface capability to systems at 5 V supply
a73 No bus current loading when output is tied to 5 V bus
