1. General description
The 74ALVT16241 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 74ALVT16241 is a 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
■ 5 V I/O compatible
■ Live insertion and extraction permitted
■ 3-state buffers
■ Power-up 3-state
■ Output capability: +64 mA and −32 mA
■ Latch-up protection:
◆ JESD 78 exceeds 500 mA
■ Electrostatic discharge protection:
◆ MIL STD 883 method 3015: exceeds 2000 V
◆ Machine model: exceeds 200 V
■ Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs
■ 16-bit bus interface
■ TTL input and output switching levels
■ Input and output interface capability to systems at 5 V supply
■ No bus current loading when output is tied to 5 V bus
