74240 Octal 3-STATE Buffer /Line Driver/Line Receiver IC PDIP-20 The 74240 Octal 3-STATE Buffer/Line Driver/Line Receiver IC PDIP-20 is an octal buffer/line driver/line receiver device designed for bus-oriented systems, memory-address driving and clock distribution, providing 3-STATE outputs, PNP inputs for reduced DC loading, input hysteresis for improved noise rejection, and a standard PDIP-20 through-hole package for easy prototyping and retrofit applications. Features: Eight buffered inverting/noninverting channels with 3-STATE outputs suitable for bus interfacing and multiplexed systems. PNP input structure reduces DC loading on data and bus lines for improved signal integrity. Input hysteresis (typically 0.2–0.4V) for enhanced noise margin at data inputs. High sink capability with typical I OL = 24mA and moderate source capability with typical I OH = −15mA. Fast switching for TTL designs with typical propagation delays in the low-tens of nanoseconds range. Low off-state leakage (I OZ typically ±20µA) to minimize bus contention when outputs are disabled. Enables driving terminated lines down to 133Ω and supports high fanout configurations.
