Obsolete TIL311 Display

Does anyone know a part that TI still makes that can be used al least similarly to the obsolete part, in other words BCD/hexadecimal input in doesn't matter if it does not have the latch enable or blanking?

Hello again Andy,

In your previous TIL313 inquiry: https://e2e.ti.com/support/interface/digital_interface/f/130/t/650847?tisearch=e2e-sitesearch&keymatch=til313 , I suggested you look though the devices available in the Discrete Segment LED Driver Product listings: www.ti.com/power-management/led-driver/discrete-segment/products.html . It seems you want something with a LATCH, so for example, I see the 'HC4511: CD74HC4511 - High Speed CMOS Logic BCD-to-7 Segment Latch/Decoder/Driver .

Please review the listing to see what best matches your overall requirements as there are many devices with LATCH capability. The Product listing has filter/sort capability to help narrow the choices. I'm sure you will find a suitable device.

Regards,

~Leonard

p.s. another suggestion is to refer to this E2E discussion: https://e2e.ti.com/support/power_management/led_driver/int-led_driver/f/194/p/87579/302677 .

I will probably use the 74HC4511 but do you know of any displays that have the decoding logic directly built in, a.k.a. decoder with the LEDS built in?

Hi Andy,

Ti does not have such a device, however, here is a reference design that is similar to what you are requesting: www.ti.com/tool/TIDA-00206
