HITACHI HD74LVC16241

HD74LVC16241
16-bit Buffers / Line Drivers with 3-state Outputs
ADE-205-073B(Z)
3rd Edition
November 1995
Description
The HD74LVC16241 has sixteen buffer drivers with three state outputs in a 48 pin package. This device is
a non inverting buffer and has two active low enables (1G, 4G), high enables (2G, 3G). 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.
