CD4503 Hex Non-Inverting Buffer with 3-State Outputs DIP-16 (CD4503 DIP IC)
The CD4503 is a high-voltage CMOS integrated circuit featuring six non-inverting buffers with 3-state outputs. It is partitioned into two sections, one with four buffers and another with two, each having its own independent output enable control to facilitate flexible data bus management.
This IC is primarily used as a bus driver for interfacing microprocessors with memory and peripheral devices. It is a common choice for Arduino electronics projects in India that require driving multiple loads or managing shared communication lines without signal interference.
