MM74HC240

MM74HC240 Inverting Octal 3-STATE Buffer September 1983 Revised August 2000 MM74HC240 Inverting Octal 3-STATE Buffer General Description The MM74HC240 3-STATE buffer utilizes advanced silicon-gate CMOS technology. It possesses high drive current outputs which enable high speed operation even when driving large bus capacitances. These circuits achieve speeds comparable to low power Schottky devices, while retaining the advantage of CMOS circuitry, i.e., high noise immunity and low power consumption. It has a fanout of 15 LS-TTL equivalent inputs. The MM74HC240 is an inverting buffer and has two active LOW enables (1G and 2G). Each enable independently controls 4 buffers. All inputs are protected from damage due to static discharge by diodes to VCC and ground. Features s Typical propagation delay: 12 ns s 3-STATE outputs for connection to system buses s Wide power supply range: 2–6V s Low quiescent supply current: 80 µA (74 Series) s Output current: 6 mA Ordering Code: Order Number MM74HC240WM MM74HC240SJ MM74HC240MTC MM74HC240N Package Number M20B M20D MTC20 N20A Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300 Wide 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.
