74AHC138-Q100; 74AHCT138-Q100 3-to-8 line decoder/demultiplexer; inverting Rev. 2 — 2 April 2014 Product data sheet 1. General description The 74AHC138-Q100; 74AHCT138-Q100 are high-speed Si-gate CMOS devices and are pin compatible with Low-power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard No. 7A. The 74AHC138-Q100; 74AHCT138-Q100 is a 3-to-8 line decoder/demultiplexer. It accepts three binary weighted address inputs (A0, A1 and A2). When enabled, it provides eight mutually exclusive outputs (Y0 to Y7) that are LOW when selected. There are three enable inputs: two active LOW (E1 and E2) and one active HIGH (E3). Every output is HIGH unless E1 and E2 are LOW and E3 is HIGH. This multiple enable function, allows easy parallel expansion of the device to a 1-of-32 (5 lines to 32 lines) decoder with just four 74AHC138-Q100; 74AHCT138-Q100 devices and one inverter. The 74AHC138-Q100; 74AHCT138-Q100 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. Unused enable inputs must be permanently tied to their appropriate active HIGH or LOW state. This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications. 2. Features and benefits Automotive product qualification in accordance with AEC-Q100 (Grade 1) Specified from 40 C to +85 C and from 40 C to +125 C Balanced propagation delays All inputs have Schmitt-trigger action Demultiplexing capability Multiple input enable for easy expansion Ideal for memory chip select decoding Inputs accept voltages higher than VCC For 74AHC138-Q100 only: operates with CMOS input levels For 74AHCT138-Q100 only: operates with TTL input levels ESD protection: MIL-STD-883, method 3015 exceeds 2000 V HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V (C = 200 pF, R = 0 ) Multiple package options 74AHC138-Q100; 74AHCT138-Q100 NXP Semiconductors 3-to-8 line decoder/demultiplexer; inverting 3.
