Pinout of TIL311 (Hexadecimal LED display with latch, decoder & driver)

Here's another pinout of a very nice but very expensive hexadecimal
LED display. It's very useful for hardware monitoring of address
and data busses and it has a character set that is much more
readable than the usual 7-segment-font (CAPITAL hex digits).

I don't know if you like to keep the pin description below the
drawing.
(By the way: This chip REALLY has two notches on top and one
on bottom!)

 Vcc1 is LED supply, Vcc2 is logic supply (both +5V).
 DPL and DPR are direct connections to the catodes of the decimal points
    (no drivers, no current limiter in between).
 BI (Blanking Input) blanks the display if HIGH.
 LE (Latch Enable) latches the digital data on D0(LSB)..D3(MSB) if HIGH.

 Pins 6, 9, 11 are missing.
