FEATURES * 5 V tolerant inputs for interfacing with 5 V logic * Wide supply voltage range from 1.2 to 3.6 V * CMOS low power consumption * Direct interface with TTL levels * Inputs accept voltages up to 5.5 V * Complies with JEDEC standard no. 8-1A * ESD protection: HBM EIA/JESD22-A114-A exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V. * Specified from -40 to +85 C and -40 to +125 C. DESCRIPTION The 74LVC157A is a high-performance, low-power, low-voltage, Si-gate CMOS device and superior to most advanced CMOS compatible TTL families.
74LVC157A
Inputs can be driven from either 3.3 or 5 V devices. This feature allows the use of these devices as translators in a mixed 3.3 and 5 V environment. The 74LVC157A is a quad 2-input multiplexer which select four bits of data from two sources under the control of a common select input (S). The four outputs present the selected data in the true (non-inverted) form. The enable input (E) is active LOW. When pin E is HIGH, all of the outputs (1Y to 4Y) are forced LOW regardless of all the other input conditions. Moving the data from two groups of registers to four common output buses is a common use of the 74LVC157A. The state of the common data select input (S) determines the particular register from which the data comes. It can also be used as function generator. The device is useful for implementing highly irregular logic by generating any 4 of the 16 different functions of two variables with one variable common. The 74LVC157A is the logic implementation of a 4-pole, 2-position switch, where the position of the switch is determined by the logic levels applied to pin S.

CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD x VCC2 x fi x N + (CL x VCC2 x fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; N = total load switching outputs; (CL x VCC2 x fo) = sum of the outputs. 2. The condition is VI = GND to VCC. input capacitance power dissipation capacitance per gate VCC = 3.3 V; notes 1 and 2 CL = 50 pF; VCC = 3.3 V CL = 50 pF; VCC = 3.3 V CL = 50 pF; VCC = 3.3 V 2.6 2.8 2.6 5.0 15 ns ns ns pF pF CONDITIONS TYPICAL UNIT
