AT 25 C VE CAPABILITY 15 LSTTL LOADS ON DELAYS tPLH = tPHL CAL OUTPUT IMPEDANCE IOL = IOH = 6 mA (MIN.) GH NOISE IMMUNITY VNIH = VNIL = 28 % VCC (MIN.) DE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V N AND FUNCTION COMPATIBLE WITH 54/74LS125/126 B1R (Plastic Package) F1R (Ceramic Package) M1R (Micro Package) C1R (Chip Carrier) ORDER CODES : M54HCXXXF1R M74HCXXXM1R M74HCXXXB1R M74HCXXXC1R The M54/74HC125/126 are high speed CMOS QUAD BUS BUFFER (3-STATE) FABRICATED IN SILICON GATE C2MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption. These devices require the same 3-STATE control input G to be taken high to make the output go into the high impedance state. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
