HD74LS248

BCD-to-Seven-Segment Decoder / Driver

(internal pull-up outputs)

REJ03D0466–0300

Rev.3.00

Jul.15.2005

The HD74LS248 is electrically and functionally identical to the HD74LS48, respectively, and has the same pin

assignments as its equivalents. It can be used interchangeably in present or future designs to offer designers a choice

between two indicator fonts. The HD74LS48 composes the 6 and the 9 without tails and the HD74LS248 composes the

6 and the 9 with tails. Composition of all other characters, including display patterns for BCD inputs above nine, is

identical. The HD74LS248 features active-low outputs designed for driving indicators directly. All of the circuits have

full ripple-blanking input / output controls and a lamp test input. Segment identification and resultant displays are

shown below. Display patterns for BCD input count 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 this type may be performed at any time when the BI / RBO node is at a high level. This type contains

an overriding blanking input (BI) which can be used to control the lamp intensity be pulsing or to inhibit the outputs.
