74HC138; 74HCT138 3-to-8 line decoder/demultiplexer; inverting Rev. 5 — 26 January 2015 Product data sheet 1. General description The 74HC138; 74HCT138 decodes three binary weighted address inputs (A0, A1 and A2) to eight mutually exclusive outputs (Y0 to Y7). The device features three enable inputs (E1, E2 and E3). Every output will be HIGH unless E1 and E2 are LOW and E3 is HIGH. This multiple enable function allows easy parallel expansion to a 1-of-32 (5 to 32 lines) decoder with just four ‘138’ ICs and one inverter. The ‘138’ can be used as an eight output demultiplexer by using one of the active LOW enable inputs as the data input and the remaining enable inputs as strobes. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. 2. Features and benefits  Complies with JEDEC standard no. 7A  Input levels:  For 74HC138: CMOS level  For 74HCT138: TTL level  Demultiplexing capability  Multiple input enable for easy expansion  Ideal for memory chip select decoding  Active LOW mutually exclusive outputs  ESD protection:  HBM JESD22-A114F exceeds 2000 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.
