MM54HC4511 MM74HC4511 BCD-to-7 Segment Latch Decoder Driver
General Description
This high speed latch decoder driver utilizes advanced silicon-gate
CMOS technology It has the high noise immunity and low power consumption of standard
CMOS integrated circuits as well as the ability to drive 10 LS-TTL loads The circuit provides the functions of a 4-bit storage latch an 8421 BCD-to-seven segment decoder and an output drive capability Lamp test (LT) blanking (Bl) and latch enable (LE) inputs are used to test the display to turn-off or pulse modulate the brightness of the display and to store a BCD code respectively It can ...
