4-bit Transparent Latch and 4-to-16 Line Decoder DIP-24
The MC14515B is a 4-to-16 line decoder with latched inputs. The MC14515B (output active low option) presents a logical "0" at the selected output. The latches are R-S type flip-flops which hold the last input data presented prior to the strobe transition from "1" to "0". These high and low options of a 4-bit latch / 4-to-16 line decoder are constructed with N-channel and P-channel enhancement mode devices in a single monolithic structure. The latches are R-S type flip-flops and data is admitted upon a signal incident at the strobe input, decoded, and presented at the output.
These complementary circuits find primary use in decoding applications where low power dissipation and/or high noise immunity is desired.
Supply voltage range: 3 VDC to 18 VDC
Capable of driving two low-power TTL loads or one low-power Schottky TTL load in the rated temperature range
