3V applications.
It has better speed performance at 3.
3V than 5V LSTTL family combined with the true CMOS low power consumption.
G and G output controls govern four BUS BUFFERs.
This device is designed to be used with 3 state memory address drivers, etc.
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
DESCRIPTION The LVQ241 is a low voltage CMOS OCTAL BUS BUFFER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.
It is ideal for low power and low noise PIN CONNECTION AND IEC LOGIC SYMBOLS February 1999 1/8 74LVQ241 INPUT AND OUTPUT EQUIVALENT CIRCUIT PIN DESCRIPTION PIN No 1 2, 4,6, 8 9, 7,5, 3 11, 13, 15, 17 18, 16, 14, 12 19 10 20 SYMBOL 1G 1A1 to 1A4 2Y1 to 2Y4 2A1 to 2A4 1Y1 to 1Y4 2G GND VCC NAME AND FUNCT ION Output Enable Input Data Inputs Data Outputs Data Inputs Data Outputs Output Enable Input Ground (0V) Positive Supply Voltage TRUTH TABLE INPUT G L L H X:”H” or ”L” Z: High impedance O UT PUT An L H X Yn L H Z G H H L ABSOLUTE MAXIMUM RATING Symbol VCC VI VO IIK IOK IO ICC orIGND Tstg TL Supply Voltage DC Input Voltage DC Output Voltage DC Input Diode Current DC Output Diode Current DC Output Current DC VCC or Ground Current Storage Temperature Lead Tempera...
