The MC54/74HC154 is identical in pinout to the LS154. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
This device, when enabled, selects one of 16 active–low outputs. Two active–low Chip Selects are provided to facilitate the chip–select, demulti­plexing, a nd cascading f unctions. When either Chip Select is h igh, all outputs are high. The demultiplexing function is accomplished by using the Address inputs to select the desired device output. Then, while holding one chip select input low, data can be applied to the other chip select input (see Application Note).
The HC154 is primarily used for memory address decoding and data routing applications.
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2 to 6 V
Low Input Current: 1 µA
High Noise Immunity Characteristic of CMOS Devices
In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
Chip Complexity: 192 FETs or 48 Equivalent Gates

NOTE: Information on typical parametric values can be found in Chapter 2 of the Motorola High–Speed CMOS Data Book (DL129/D).
This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high–impedance cir­cuit. For proper operation, Vin and V
out
should be constrained to the
range GND v (Vin or V
out
) v VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.

PIN DESCRIPTIONS
INPUTS A0, A1, A2, A3 (Pins 23, 22, 21, 20)
Address inputs. These inputs, when the 1–of–16 decoder is enabled, determine which of its sixteen active–low outputs is selected.
OUTPUTS Y0 – Y15 (Pins 1 – 11, 13 – 17)
Active–low outputs. These outputs assume a low level
when addressed and both chip–select inputs are active. These outputs remain high when not addressed or a chip– select input is high.
CONTROL INPUTS CS1, CS2 (Pins 18, 19)
Active–low chip–select inputs. With low levels on both of these inputs, the outputs of the decoder follow the Address inputs. A high level on either input forces all outputs high.
