The 74LS243 is a low-power Schottky TTL IC with four non-inverting bidirectional bus transceivers. Two separate enable inputs (one active-low, one active-high) select whether data flows from A to B or from B to A, or whether both sides are in the high-impedance (3-state) condition. Its inverting sibling is the 74LS242. It runs from a 5 V supply. It comes in a 14-pin plastic DIP.
Condition: mixed surplus lot, untested. The bag may contain used (pulled) ICs of the same type from different manufacturers, so marking and date code vary. The photo shows one chip from this lot (74LS243N 8219 SA); only the background was cleaned to white, preserving the marking and leads.
Minimum order: 1 pc.
