topGeneral description
The 74HC/HCT4511 are high-speed Si-gate CMOS devices and are pin compatible with '4511' of the '4000B' series.
They are specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT4511 are BCD to 7-segment latch/decoder/drivers with four address inputs (D1 to D4), an active
LOW latch enable input (LE), an active LOW ripple blanking input (BI), an active LOW lamp test input (LT), and
seven active HIGH segment outputs (Qa to Qg).
When LE is LOW, the state of the segment outputs (Qa to Qg) is determined by the data on D1 to D4.
When LE goes HIGH, the last data present on D1 to D4 are stored in the latches and the segment outputs remain
stable.
When LT is LOW, all the segment outputs are HIGH independent of all other input conditions. With LT HIGH, a
LOW on BI forces all segment outputs LOW. The inputs LT and BI do not affect the latch circuit.
