The NTE74LS248 is a BCD-to-Seven-Segment Decoder/Driver in a 16-lead plastic DIP-type package incorporating automatic leading and/or trailing-edge zero-blanking control (RBI and RBO). Lamp test (LT) may be performed at any time when the BI/RBO node is at a high level. This device also contains an overriding blanking input (BI) which can be used to control the lamp intensity by pulsing or to inhibit the outputs. Inputs and outputs are entirely compatible for use with TTL logic outputs.
Internal pull−ups eliminate the need for external resistors
