5442A Datasheet | National Semiconductor

Description These BCD-to-decimal decoders consist of eight inverters and ten four-input NAND gates The inverters are connected in pairs to make BCD input data available for decoding by the NAND gates Full decoding of input logic ensures that all outputs remain off for all invalid (10- 15) input conditions Features Diode clamped inputs Also for application as 4-line-to-16-line decoders 3-lineto-8-line decoders All outputs are high for invalid input conditions Typical power dissipation 140 m W Typical propagation delay 17 ns Alternate Military Aerospace device (5442A) is available Contact a National Semiconductor Sales Office Distributor for specifications Connection Diagram Dual-In-Line Package TL F 6516 - 1 Order Number 5442ADMQB 5442AFMQB DM5442AJ DM5442AW or DM7442AN See NS Package Number J16A N16E or W16A Function Table No D 0 1 2 3 4 5 6 7 8 9 I N V A L I D L L L L L L L L H H H H H H H H BCD Input C L L L L H H H H L L L L H H H H B L L H H L L H H L L H H L L H H A L H L H L H L H L H L H L H L H 0 L H H H H H H H H H H H H H H H 1 H L H H H H H H H H H H H H H H 2 H H L H H H H H H H H H H H H H Decimal Output 3 H H H L H H H H H H H H H H H H 4 H H H H L H H H H H H H H H H H 5 H H H H H L H H H H H H H H H H 6 H H H H H H L H H H H H H H H H 7 H H H H H H H L H H H H H H H H 8 H H H H H H H H L H H H H H H H 9 H H H H H H H H H L H H H H H H H e High Level L e Low Level C1995 National Semiconductor Corporation TL F 6516 RRD-B30M105 Printed in U S A Absolute Maximum Ratings (Note) If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Supply Voltage 7V Input Voltage 5 5V Operating Free Air Temperature Range b 55 C to a 125 C DM54 and 54 DM74 0 C to a 70 C Storage Temperature Range b 65 C to a 150 C Note The ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed The device should not be...
