MOTOROLA Semiconductor MC10E150/MC100E150 handbook(1)
Datasheet
The MC10E/100E150 is a 6-bit D latch with differential outputs. When both Latch Enables (LEN1, LEN2) are LOW, the latch is transparent and input data transitions propagate through to the output. A logic HIGH on either LEN1 or LEN2 (or both) latches the data. The Master Reset (MR) overrides all other controls to set the Q outputs low.
