HD74LV157A
Quad. 2-to-1 line Data Selectors / Multiplexers
(Noninverted Outputs)
ADE-205-263 (Z)
1st Edition
March 1999
Description
The HD74LV157A has four 2-input digital multiplexers with common select and strobe inputs. When the
strobe input is low, a 4-bit word is selected from one of two sources and is routed to the four outputs.
The device provides true data.
Low-voltage and high-speed operation is suitable for the battery-powered products (e.g., notebook
computers), and the low-power consumption extends the battery life.
Features
• V_CC = 2.0 V to 5.5 V operation
• All inputs V_IH (Max.) = 5.5 V (@V_CC = 0 V to 5.5 V)
• All outputs V_O (Max.) = 5.5 V (@V_CC = 0 V)
• Typical V_OL ground bounce < 0.8 V (@V_CC = 3.3 V, Ta = 25°C)
• Typical V_OH undershoot > 2.3 V (@V_CC = 3.3 V, Ta = 25°C)
• Output current ±6 mA (@V_CC = 3.0 V to 3.6 V), ±12 mA (@V_CC = 4.5 V to 5.5 V)
