MH8808 Datasheet dual high speed MOS clock driver

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: o00 00 00 Memory/Clock Drivers :::t :E MH8808 dual high speed MOS clock driver.

General Description

The MH8808 IS a high speed dual MOS clock driver intended to drive the two phases of a memory array of 500 pF per phase at rates up to 4 MHz.

The design Includes output current limit· Ing for controlled rise and fall times, and thermal shutdown which protects the chip against excessive power dissipation or accidental output shorts.

Two DTL!TTL compatible status outputs monitor clock outputs and provide a corresponding TTL logic level for status indication.

Key Features

  • High Speed: 18 ns typ delay and 20 ns typ rise and fall times with 500 pF load.
  • Current limited outputs ±450 mA typ.
  • Direct and damped outputs available.
  • Thermal shutdown protection.
  • TTL compatible status outputs.
  • 1W dissipation capability at 25°.
