1. general description the 74hc151; 74hct151 are 8-bit multiplexer wit h eight binary inputs (i0 to i7), three select inputs (s0 to s2) and an enable input (e ). one of the eight binary inputs is selected by the select inputs and routed to the complementary outputs (y and y ). a high on e forces the output y low and output y high. inputs also include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of v cc . 2. features and benefits ? specified in compliance with jedec standard no. 7a ? input levels: ? for 74hc151: cmos level ? for 74hct151: ttl level ? low-power dissipation ? non-inverting data path ? esd protection: ? hbm jesd22-a114f exceeds 2 000 v ? mm jesd22-a115-a exceeds 200 v ? multiple package options ? specified from ? 40 ? c to +85 ? c and from ? 40 ? c to +125 ? c 3. ordering information 74hc151; 74hct151 8-input multiplexer rev. 5 ? 26 january 2015 product data sheet table 1. ordering information type number package temperature range name description version 74hc151n ? 40 ? c to +125 ? c dip16 plastic dual in-line package; 16 leads (300 mil) sot38-4 74hct151n 74hc151d ? 40 ? c to +125 ? c so16 plastic small outline package; 16 leads; body width 3.9 mm sot109-1 74hct151d 74hc151db ? 40 ? c to +125 ? c ssop16 plastic shrink sma ll outline package; 16 leads; body width 5.3 mm sot338-1 74hct151db 74hc151pw ? 40 ? c to +125 ? c tssop16 plastic thin shrink small outline package; 16 leads; body width 4.4 mm sot403-1 74hct151pw
