Enclosed is the new layout to be added to the logic tests.
The test was performed on the UCY74S416 (4-bit data bus transmitter/receiver) chip from Unitra CEMI (Poland).

At the next software update, please change the name of the 74416 chip to 74S416 in the Logic IC Tester module. It turned out that there is also a chip named 74416 (modulo 10 counter, preload and clear inputs, for example MC74416) which has different functionality than 74S416 (UCY74S416, 4-bit bidirectional bus transceiver, non-inverting three-state [equivalent to Intel 8216]).
