DESCRIPTION/ORDERING INFORMATION
SN54LVC157A, SN74LVC157A
QUADRUPLE 2-LINE TO 1-LINE DATA SELECTORS/MULTIPLEXERS
SCAS292P – JANUARY 1993 – REVISED JULY 2005
Operate From 1.65 V to 3.6 V
Latch-Up Performance Exceeds 250 mA Per
JESD 17
Specified From –40
°C to 85°C,
–40
°C to 125°C, and –55°C to 125°C
ESD Protection Exceeds JESD 22
Inputs Accept Voltages to 5.5 V
– 2000-V Human-Body Model (A114-A)
Max t
pd of 5.2 ns at 3.3 V
– 200-V Machine Model (A115-A)
Typical V
OLP (Output Ground Bounce)
– 1000-V Charged-Device Model (C101)
< 0.8 V at V
CC = 3.3 V, TA = 25°C
BRK
Typical V
OHV (Output VOH Undershoot)
> 2 V at V
CC = 3.3 V, TA = 25°C
These quadruple 2-line to 1-line data selectors/multiplexers are designed for 1.65-V to 3.6-V VCC operation.
The 'LVC157A devices feature a common strobe (G) input. When G is high, all outputs are low. When G is low, a
4-bit word is selected from one of two sources and is routed to the four outputs. The devices provide true data.
