No Preview Available ! HD74HCT238 3-to-8-line Decoder/Demultiplexer Description The HD74HCT238 has 3 binary select inputs (A, B, and C). If the device is enabled these inputs determined which one of the eight normally high outputs will go low. Two active low and one active high enables (G1, G2A and G2B) are provided to ease the cascading of decoders. Features • LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility • High Speed Operation: tpd (A, B, C to Y) = 18.5 ns typ (CL = 50 pF) • High Output Current: Fanout of 10 LSTTL Loads • Wide Operating Voltage: VCC = 4.5 to 5.5 V • Low Input Current: 1 µA max • Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) 1 page 19.20 20.00 Max 16 9 1 1.3 1.11 Max 8 Unit: mm 7.62 2.54 ± 0.25 0.48 ± 0.10 0.25 + – 0.13 0.05 0° – 15° Hitachi Code JEDEC EIAJ Weight (reference value) DP-16 Conforms Conforms 1.07 g 5 Page
