INTEGRATED CIRCUITS 74LV138 3-to-8 line decoder/multiplexer; inverting Product specification Supersedes data of 1997 Feb 03 IC24 Data Handbook 1998 Apr 28 Philips Semiconductors Product specification 3-to-8 line decoder/demultiplexer; inverting FEATURES 74LV138 DESCRIPTION • Wide operating voltage: 1.0 to 5.5 V • Optimized for low voltage applications: 1.0 to 3.6 V • Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V • Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V, The 74LV138 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC/HCT138. The 74LV138 accepts three binary weighted address inputs (A0, A1, A2) and when enabled, provide 8 mutually exclusive active LOW outputs (Y0 to Y7). Tamb = 25°C The 74LV138 features three enable inputs: two active LOW (E1, and E2) and one active HIGH (E3). Every output will be HIGH unless E1 and E2 are LOW and E3 is HIGH. • Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V, Tamb = 25°C • Demultiplexing capability • Multiple input enable for easy expansion • Ideal for memory chip select decoding • Active LOW mutually exclusive outputs • Output capability: standard • ICC category: MSI This multiple enable function allows easy parallel expansion of the 74LV138 to a 1-of-32 (5 lines to 32 lines) decoder with just four 74LV138 ICs and one inverter. The 74LV138 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. The 74LV138 is identical to the 74LV238 but has non-inverting (true) outputs.
