DP84240/DP84244 Octal TRI-STATE MOS Drivers

General Description

Features

specified with 250 pF and 500 pF loads

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.

Output specified from 0.8V to 2.7V

Designed for symmetric rise and fall times at 500 pF

Outputs glitch free at power up and power down

PNP inputs reduce DC loading on bus lines

Low static and dynamic input capacitance

Low skew times between edges and pins

AC parameters specified with all outputs switching

simultaneously
