2-channel analog multiplexer/demultiplexer

Rev. 01 — 7 February 2005

Product data sheet

1. General description

The 74LVC1G3157 is a high-performance, low-power, low-voltage, Si-gate CMOS device

that provides superior performance to most advanced CMOS compatible TTL families.

The 74LVC1G3157 provides one analog multiplexer/demultiplexer with one digital select

input (S), two independent inputs/outputs (B1 and B2) and a common input/output (A).

2. Features

■ Wide supply voltage range from 1.65 V to 5.5 V

■ Very low ON-resistance:

◆ 7.5 Ω (typical) at V_CC= 2.7 V

◆ 6.5 Ω (typical) at V_CC= 3.3 V

◆ 6 Ω (typical) at V_CC= 5 V

■ Break-before-make switching

■ High noise immunity

■ ESD protection:

◆ HBM EIA/JESD22-A114-B exceeds 2000 V

◆ MM EIA/JESD22-A115-A exceeds 200 V

■ CMOS low-power consumption

■ Latch-up performance meets requirements of JESD 78 Class I

■ Direct interface with TTL levels

■ Control input accepts voltages up to 5 V

■ Multiple package options

■ Speciﬁed from −40 °C to +85 °C and from −40 °C to +125 °C
