Description
The 74LS49 features active-high outputs for driving lamp buffer. This circuit incorporates a direct blanking input. Segment identification and resultant displays are shown below. Display patterns for BCD input counts above 9 are unique symbols to authenticate input conditions. It contains an over-riding blanking input ( BI ) which can be used to control the lamp intensity by pulsing or to inhibit the output. Inputs and outputs are entirely compatible for use with TTL or DTL logic outputs.
