RD74LVC16240B
16-bit Buffers / Line Drivers with 3-state Outputs
REJ03D0526-0100 Rev.1.00 Mar. 14, 2005
Description
The RD74LVC16240B has sixteen inverter drivers with three state outputs in a 48 pin package. This device is a inverting buffer and has two active low enables (1G to 4G). Each enable independently controls four buffers. Low voltage and high-speed operation is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation.
