MC100H641 Overview
The device 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 patible with positive MECL 10H™ logic levels. The 100H version is
