DP84240DP84244 Octal TRI-STATE

MOS Drivers

General Description

The DP84240 and DP84244 are octal TRI-STATE drivers

which are designed for heavy capacitive load applications

such as fast data buffers or as memory address drivers The

DP84240 is an inverting driver which is pin-compatible with

both the 74S240 and AM2965 The DP84244 is a non-in-

verting driver which is pin-compatible with the 74S244 and

AM2966 These parts are fabricated using an oxide isolation

process for much faster speeds and are specified for

250 pF and 500 pF load capacitances
