MM5453N LCD or LED ?

That part is an LCD driver, so you'll not get far with an LED display.

You want a static (not multiplexed) LCD display. The multiplexed type (with more than one backplane will NOT work). Try Mouser. Note that that chip can only drive 32 segments, so it cannot drive all the segments of a 6 digit display.

Spehro This is the display for a Lowe HF-235 receiver made in the UK. The last five characters are used to display tuned frequency up to 29.999 MHz and the first character is used to display status using segments D,F,G. I wonder how they accomplish that if the MM5453 can only drive 32 segments? tnx

Are there two MM5453s? Or perhaps they implemented it with discrete logic (look for the CMOS XOR or XNOR gates such as CD4070/4077). That's all it takes to drive a static LCD segment once you've got a

BTW, there's a pin-type 18mm 'Lumex' LCD on the website I referenced that might do *if* you can make it fit mechanically and if you don't mind wiring up all those pins.

No there is only one 5354 and I've got a schemtic of that part in an 82 page pdf but I can't get one page out to send it you. The enitre manual is on mods.dk. If I figure it out I 'll send it so you can look it over and give me a better opinion. tnx

I think I have it figured out. The Lowe HF-235 radio can tune up to X29.999MHz, where X is used as a status indicator and driven by an exclusive-or gate. For display of frequency the leading or most significant digit of the five can only be a one or a two. For a one bits 31 and 32 drive segments b and c. Segments a,d,e,g are tied together and bits 31 and
