BCD to DEC TTL converter

BCD to DEC TTL converter

Simply but powerful converter/decoder from BCD data in TTl logic to one of eight. You can use it everywhere you have less wires than you need.

Using

Universal converter/decoder BCD to DEC
Compatible with Ameritron switches
When you miss wires to your tower :)
Remote control expander

Main functions

BCD to DEC matrix table
Outputs 0 to 7 or 1 to 8 (jumper)
Universal OUTPUT: + or GND
BCD input HIGH with 2.6 to 9 V - designed for TTL logic
TBD and ULN drivers are included
RF and high voltage protections
ASSEMBLED and TESTED VERSION

Parameters

Output current max. 500 mA
Voltage drop for TBD driver typ. 0.2V for +12V input and 0.6V for BCD wires power input
Voltage drop for ULN driver typ. 0.8V for +12V input and 1.3V for BCD wires power input
Input voltage > 13V is recommended for 12V relays
Control voltage for BCD input is TTL (2.6 to 9 V for active HIGH)
Low loss in switching driver
Universal output switching: to GND or + Vcc
Output 0 for 0000 BCD or 8 for 0001 - easy select by jumper
Compatible with microHAM ACC
PCB size 90x52 mm

Available as

ASSEMBLED: ready to use

Included in package

BCD assembled and tested

Matrix table for inputs and outputs

Connection of control cables and power supply

- with external power voltage wire
- one more wire
- BCD wires can use smaller voltage 2.6 to 9 V
- for longer distance

Output 0 to 8

- compatible with MFJ antenna switch
- easy to set by jumper

Output driver

- universal outputs - switching to GND or + voltage
- easy to set by jumper
- easy to replace driver ULN (- out) / TBD (+ out)

Example with 6-to-1

- need four (five) wires between controller and BCD to DEC converter
- GND, (+12V) and three control wires
- output must be with TBD driver (+ out)

Example with 4-to-1

- need four (three) wires between controller and BCD to DEC converter
- GND, (+12V) and three control wires
- output must be with TBD driver (+ out)

Example with microHAM devices

- need four (three) wires between controller and BCD to DEC converter
- GND, (+12V) and three control wires
- output must be with TBD driver (+ out)

Example with 6-to-2 microHAM devices

- need four (three) wires between controller and BCD to DEC converter
- GND, (+12V) and three control wires
- output must be with TBD driver (+ out)
