00 Mar 30, 2006 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 • High Speed Operation: tpd (A, B, C to Y) = 16.
5 ns typ (CL = 50 pF) • High Output Current: Fanout of 10 LSTTL Loads • Wide Operating Voltage: VCC = 2 V to 6 V • Low Input Current: 1 µA max • Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) • Ordering Information Part Name Package Type Package Code (Previous Code) Package Abbreviation HD74HCT238FPEL SOP-16 pin (JEITA) PRSP0016 DH-B (FP-16DAV) FP PRSP0016 DG-A HD74HCT238RPEL SOP-16 pin (JEDEC) (FP-16DNV) RP Note: Please consult the sales office for the above package availability.
