74AC125
74AC125 is Quad Buffer manufactured by Fairchild Semiconductor.
DESCRIPTION The AC125 is an high-speed CMOS QUAD BUS BUFFERS fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power applications maintaining high speed operation similar to PIN CONNECTION AND IEC LOGIC SYMBOLS May 1997 1/8 INPUT AND OUTPUT EQUIVALENT CIRCUIT PIN DESCRIPTION PIN No 1, 4, 10, 13 2, 5, 9, 12 3, 6, 8, 11 7 14 SYMBOL G1 to G4 A1 to A4 Y1 to Y4 GND VCC NAME AND F UNCTIO N Output Enable Inputs Data Inputs Data Outputs Ground (0V) Positive Supply Voltage TRUTH TABLE A X L H G H L L Y Z L H ABSOLUTE MAXIMUM RATINGS Symbol VCC VI VO IIK IOK IO Tstg TL Supply Voltage DC Input Voltage DC Output Voltage DC Input Diode Current DC Output Diode Current DC Output Current Storage Temperature Lead Temperature (10 sec) Parameter Value -0.5 to +7 -0.5 to VCC + 0.5 -0.5 to VCC + 0.5 ± 20 ± 20 ± 50 ± 200 -65 to +150 300 Unit V V V m A m A m A m A o o ICC or IGND DC VCC or Ground Current Absolute Maximum Ratings are those values beyond which damage to the device may occur.
