MC100H641 Overview
Key Features
- a 24mA TTL output stage, with AC performance specified into a 50pF load capacitance
- A latch is provided on–chip
- When LEN is LOW (or left open, in which case it is pulled LOW by the internal pulldown) the latch is transparent
- A HIGH on the enable pin (EN) forces all outputs LOW
- Both the LEN and EN pins are positive ECL inputs
- The VBB output is provided in case the user wants to drive the device with a single–ended input
- For single–ended use the VBB should be connected to the D input and bypassed with a 0.01µF capacitor
- The 10H version of the H641 is compatible with positive MECL 10H™ logic levels
- The 100H version is com
