M74HC243規(guī)格書詳情
DESCRIPTION
The M54/74HC242/243 are high speed CMOS QUAD BUS TRANSCEIVER (3-STATE) FABRICATED IN SILICON GATE C2MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption. The HC242/243 are 3 STATE bi-directional inverting and non-inverting buffers and are intended for two-way asynchronous communication between data buses. They are high drive current outputs which enable high speed operation when driving large bus capacitances.
■ HIGH SPEED tPD = 9 ns (TYP.) AT VCC = 5 V
■ LOW POWER DISSIPATION ICC = 4 μA (MAX.) AT 25 °C
■ OUTPUT DRIVE CAPABILITY 15 LSTTL LOADS
■ BALANCED PROPAGATION DELAYS tPLH = tPHL
■ SYMMETRICAL OUTPUT IMPEDANCE IOL = ?IOH? = 6 mA (MIN.)
■ HIGH NOISE IMMUNITY VNIH = VNIL = 28 VCC (MIN.)
■ WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V
■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS242/243
