HD74LS48 Datasheet | Renesas

BCD-to-Seven-Segment Decoder / Driver (Internal Pull-up outputs) REJ03D0411- 0300 Rev.3.00 Jul.22.2005 HD74LS48 Features active high outputs for driving lamp buffers. This circuit has full ripple blanking input / output controls and a lamp test input. Display patterns for BCD input counts above 9 are unique symbols to authenticate input conditions. This circuit incorporates automatic leading and / or trailing-edge zero-blanking control (RBI and RBO). Lamp test (LT) of these types may be performed at any time when the BI / RBO node is at a high level. It contains an overriding blanking input (BI) which can be used to control the lamp intensity be pulsing or to inhibit the outputs....
