The display mode of the BCD input count greater than 9 is the only symbol that validates the input condition. All of these circuits contain automatic guidance and/or tracking edae zero blanking controls (RBI and RBO). These types of lamp tests (CT) can be performed at any time when the bF/RBO node is at high power. The AH type contains an overlay blanking input (BO), which can be used to control the tile lamp intensity or suppress the output through pulses. Input and output are fully compatible with TTL logical output. Series 74LS devices feature from 0°C to 70°C.
