BCD-to-Seven Segment Latch/Decoder/Driver

Description

The HD74HC4511 provides the functions of a 4-bit storage latch, a BCD-to-seven-segment decoder, and

an output driver. Lamp test (LT), blanking (BI), 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.

Features

• High Speed Operation: tpd (A, B, C, D to a – g) = 31 ns typ (CL = 50 pF)

• High Output Current: Fanout of 10 LSTTL Loads

• Wide Operating Voltage: VCC = 2 to 6 V

• Low Input Current: 1 µA max

• Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
