[ /Title (CD74 HC137 , CD74 HCT13 7, CD74 HC237 , CD74 HCT23 7) /Subject (High Speed Data sheet acquired from Harris Semiconductor SCHS146F March 1998 - Revised October 2003 CD74HC137, CD74HCT137, CD54HC237, CD74HC237, CD74HCT237 High-Speed CMOS Logic, 3- to 8-Line Decoder/Demultiplexer with Address Latches Features Both circuits have three binary select inputs (A0, A1 and A2) that can be latched by an active High Latch Enable (LE) signal to isolate the outputs from select-input changes. A “Low” LE makes the output transparent to the input and the circuit functions as a one-of-eight decoder. Two Output Enable inputs (OE1 and OE0) are provided to simplify cascading and to facilitate demultiplexing. The demultiplexing function is accomplished by using the A0, A1, A2 inputs to select the desired output and using one of the other Output Enable inputs as the data input while holding the other Output Enable input in its active state. In the CD74HC137 and CD74HCT137 the selected output is a “Low”; in the ’HC237 and CD74HCT237 the selected output is a “High”. • Select One of Eight Data Outputs - Active Low for CD74HC137 and CD74HCT137 - Active High for ’HC237 and CD74HCT237 • l/O Port or Memory Selector • Two Enable Inputs to Simplify Cascading • Typical Propagation Delay of 13ns at VCC = 5V, 15pF, TA = 25oC (CD74HC237) • Fanout (Over Temperature Range) - Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads - Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads Ordering Information • Wide Operating Temperature Range . . . -55oC to 125oC • Balanced Propagation Delay and Transition Times TEMP.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. Addendum-Page 2 PACKAGE OPTION ADDENDUM www.ti.com 9-Oct-2007 TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
